Ledger wallet security settings should make unauthorized access harder without adding recovery steps you cannot manage. Set a private PIN, use the device’s available lock or screen-saver behavior, keep Ledger OS current, and protect your Secret Recovery Phrase offline. Leave blind signing and Smart account upgrade off unless a transaction you deliberately intend to make requires them. The exact menu and available controls depend on the Ledger model and software version, so treat the device’s own options and model-specific support instructions as authoritative.
Which Ledger security settings should you enable?
For routine use, prioritize the settings and habits that protect access to the device and prevent careless transaction approvals. On the Nano X and Nano S Plus, Ledger’s navigation guide lists Change PIN, Passphrase, PIN lock, and screen saver in the Security menu. Other Ledger models may expose different settings or use different paths; do not assume every device has the same controls.

- Set a device PIN during setup and keep it private. Change it if you believe someone else knows it.
- Use the available PIN-lock or screen-saver behavior so an unattended device does not simply remain open. Choose from the options available on your model; there is no single timeout or menu path that applies to every Ledger device.
- Keep Ledger OS current by checking the version on the device and following the official instructions for your model.
- Keep the Secret Recovery Phrase private and offline. Do not type it into a website, chat, email, or software wallet, and do not disclose it to someone claiming to be support.
- Review transaction details on the device screen before approving. Reject a transaction if the displayed details do not match what you intend to do.
- Leave advanced transaction settings off by default. Enable one only when a trusted application and a transaction you intend to make require it, then turn it off again when possible.
The main distinction is between routine access protections and optional capabilities. A PIN, available locking behavior, software updates, phrase protection, and careful on-device review are sensible baseline practices. Passphrases and smart-contract settings add capabilities, but also add complexity or approval risk; they are not general-purpose “more secure” switches for every owner.
How do I set a PIN and use the device lock?
Set a PIN when initializing the wallet, and use the lock or screen-saver option available on your device. These controls help protect access when the device is unattended, but they do not replace keeping your recovery phrase secret.

For Nano X and Nano S Plus, consult Ledger’s navigation menu map for the Security menu and its listed options. It includes Change PIN, PIN lock, and screen saver. Use the guide for your actual model rather than following button-by-button directions written for a different device; Ledger’s menu paths vary by device family and software version.
Choose a PIN that you can enter accurately but that another person cannot easily guess from information they know about you. Do not share it or leave it written beside the device. If you think someone has learned it, change it using the device’s own settings. The supplied guidance does not establish a universal PIN length or lock timeout, so follow the options and instructions currently shown for your model rather than relying on a generic number from an older guide.

The device screen still matters each time you authorize an operation. Treat the PIN and lock as one layer of a broader routine, not as a reason to skip checking what the device asks you to confirm.
Should I enable a passphrase?
A passphrase is an advanced option, not a required security setting for every Ledger owner. Use it only if you understand its recovery implications and have a dependable way to preserve the exact passphrase as well as your recovery phrase.
Ledger lists Passphrase in the Security menu for the Nano X and Nano S Plus. A passphrase creates access to corresponding accounts that depends on both the Secret Recovery Phrase and the exact passphrase. In practice, that means the recovery phrase alone is not enough to recover access to those passphrase-linked accounts if you later cannot supply the passphrase exactly.
This option can be appropriate for someone who deliberately wants the additional account separation it provides and has planned how to recover it. It can also create a serious self-inflicted access problem if the passphrase is forgotten, recorded inaccurately, or not included in a recovery plan. Protecting the passphrase does not reduce the importance of protecting the underlying recovery phrase, and the passphrase is not a substitute for it.

If you are unsure whether you can reliably maintain both recovery details, leave the passphrase feature unused. A simpler setup that you can recover correctly is preferable to adding an advanced option without understanding its consequences. Before enabling it, read Ledger’s current instructions for your exact device and make sure you understand how the accounts you use would be restored.
When should I enable blind signing?
Keep blind signing disabled by default. Enable it only when a specific smart-contract transaction you intend to make requires it, and disable it again afterward if the setting remains available.
Ledger describes blind signing as an advanced feature used for some smart-contract transactions, including some decentralized-exchange swaps. If a trusted application tells you it is needed, treat that as a compatibility requirement for that transaction—not a reason to leave the setting on indefinitely. Ledger’s Ethereum (ETH) support guidance explains the setting and recommends disabling it after use.
Before approving, inspect the information shown on the hardware wallet. Ledger’s navigation guide says to review the transaction type, amount, and fees, scroll through the recipient address, and approve only at the final confirmation screen. If the display does not match your intention, stop and reject the transaction. Do not approve an unfamiliar request simply because a website, application, or message says that approval is necessary.
Recommended Free Tools
Ledger says a Ledger OS update or Ethereum app update automatically disables blind signing. If a transaction that previously worked now requires the setting again, check the official support instructions and the prompt on your device rather than assuming the feature should stay on permanently.
What is Smart account upgrade, and should I turn it on?
Most users should leave Smart account upgrade off. Ledger describes it as an Ethereum app setting for EIP-7702 authorizations, smart-contract delegation, and type 4 transactions, and says it is disabled by default and intended for advanced users.
Also popular on Amazon
Enable it only if you intentionally need that capability and understand the authorization you are being asked to approve. It is not a general setting for improving routine wallet security, and turning it on does not remove the need to examine transaction details. If you do not recognize the feature or cannot explain why a particular transaction needs it, do not enable it or approve the request; consult Ledger’s official Ethereum guidance first.
Blind signing and Smart account upgrade are related in that both concern advanced transaction capabilities, but they are not interchangeable settings. Follow the requirement for the particular action you intend to take, and avoid turning on multiple advanced features just in case. Keeping unnecessary options disabled reduces the chance of approving something you did not mean to authorize.

Check the Ledger OS version on your device and compare it with the release notes and update instructions for that exact model. Ledger says updates provide security upgrades, features, and applications, but there is no single version number that safely describes every device family.
Use Ledger’s official instructions for checking the Ledger OS version. They cover Nano devices as well as Flex, Stax, and Nano Gen5, and the steps differ among device families. Check the model-specific release notes rather than relying on a version number copied from an older article or instructions for another model.
Use the official Ledger Wallet application and Ledger support instructions to manage updates. Be cautious of unsolicited links or messages claiming that an urgent update requires you to reveal your recovery phrase. Ledger Support says it will never ask for that phrase. An update request should never be a reason to type the phrase into a website, chat, email, or software wallet.
How do I protect my Secret Recovery Phrase?
Treat the Secret Recovery Phrase as a critical recovery credential: keep it private, do not enter it online, and do not share it with anyone claiming to help. Ledger’s device-failure guidance explicitly says it does not recommend entering the phrase into an online wallet, and its Contact Us page warns: “Never share your 24-word Secret Recovery Phrase, even with Ledger Support.” It also says Ledger Support will never ask for it.

That warning applies even when a message looks official or claims there is a problem with an account, device, update, or transaction. Do not send the phrase through a support form, chat, email, or website, and do not disclose it to a person who contacts you first. If you need help, use Ledger’s official support channel without revealing the phrase.
The recovery phrase is separate from device-menu settings such as the PIN or screen saver. A device lock does not make it safe to disclose, and adding a passphrase does not replace the recovery phrase. Keep the recovery information accessible to you for legitimate recovery, but inaccessible to other people and online services.
How should I review a transaction before approving it?
Use the hardware wallet’s screen as the final place to verify what you are authorizing. Check the transaction type, amount, and fees, scroll through the full recipient address, and approve only at the final confirmation screen, as Ledger’s device navigation guide instructs.
Do not rely only on a website or app display when the wallet asks you to confirm on-device. Compare the details on the hardware wallet with the action you meant to take. If the recipient, amount, fee, transaction type, or other displayed detail is unexpected, reject the request and investigate before trying again. The device screen is a checkpoint for your decision, not a formality to click through.
This review habit is especially important when an advanced feature is involved. Blind signing is intended for some smart-contract transactions, but Ledger still recommends examining device details and turning blind signing off after its needed use. If you cannot understand the authorization or verify that it matches your intention, do not approve it.

No. A factory reset is not a routine hardening step. Ledger says a reset removes the private keys, applications, and settings stored on the device, so make sure you understand how you will recover access before proceeding.

Ledger documents resets initiated through device settings or after three consecutive incorrect PIN attempts. Those are reset routes, not recommended maintenance steps. If you are considering a reset because of a suspected problem, first confirm that you have your recovery method and understand how to use it. Read the current factory reset instructions for the device rather than improvising from directions for another model.
If the device fails, Ledger’s guidance is to restore with a new Ledger device when the existing one is not operational. Its device-failure guidance also cautions against entering the recovery phrase into an online wallet. A reset or replacement is therefore a recovery situation to plan for, not a shortcut that makes the wallet inherently safer.
Which settings should stay off unless I need them?
Leave optional advanced capabilities disabled until there is a specific, understood reason to enable them. The key exception in Ledger’s guidance is blind signing for some smart-contract transactions; Smart account upgrade is also described as an advanced, default-off feature.
| Setting or practice | Routine recommendation | When to reconsider |
|---|---|---|
| PIN and available lock behavior | Set a private PIN and use the device’s available lock or screen-saver controls. | Change the PIN if you believe it has been exposed; consult your model’s instructions for the available controls. |
| Passphrase | Optional; do not enable casually. | Consider only if you understand that recovery depends on both the recovery phrase and exact passphrase, and have a reliable recovery plan. |
| Blind signing | Off by default. | Enable for a trusted smart-contract transaction that requires it; turn it off afterward when possible. |
| Smart account upgrade | Off by default. | Enable only for an intentional EIP-7702 authorization or other use you understand. |
| Ledger OS | Keep current for your model. | Check the model-specific version information and official update instructions. |
| Secret Recovery Phrase | Private and offline; never disclose it. | Use only in a legitimate recovery process on an appropriate hardware device, not as a response to a support message or online prompt. |
Bluetooth is a model-specific control: Ledger’s navigation information identifies it as an option on the Nano X. The available official guidance does not support treating Bluetooth disablement as a universal security requirement or claiming that turning it off materially improves custody security. Focus on the controls and instructions that apply to your model rather than applying one device’s settings checklist to every Ledger wallet.
What is the simplest safe setup?
Start with the baseline: set a private PIN, use the available device lock, keep the operating system current using official model-specific instructions, and protect the recovery phrase from people and online services. Leave passphrase, blind signing, and Smart account upgrade alone unless you understand a concrete need and the recovery or transaction consequences.
For every transaction, compare the device’s transaction type, amount, fees, and full recipient address with your intention. Stop if the information is wrong, unexpected, or impossible for you to verify. If you need to reset or replace a device, plan recovery first and follow Ledger’s device-specific guidance; do not turn a reset into a routine security ritual.
Frequently Asked Questions
Do I need to enable blind signing for every crypto transaction?
No. Ledger describes blind signing as necessary for some smart-contract transactions, not as a general requirement for routine transactions. If an application says it is needed, verify that you recognize and intend the transaction before changing the setting.
Can I use Ledger Support to check whether my recovery phrase is correct?
Do not send or disclose the phrase to support for verification. Ledger says its support staff will never ask for the 24-word phrase; if you need help, contact support without including it.
Does turning off Bluetooth make every Ledger wallet safer?
The official guidance identifies Bluetooth as a Nano X option, not a universal control across Ledger models. It does not establish that disabling Bluetooth materially improves custody security, so follow the instructions for your own device rather than treating it as a required setting.
