Vault Timeout Options
Vault Timeout behavior will determine how your Vault will behave after a customizable period of inactivity. Timeout is configured individually from and for each Bitwarden client application that you use (Mobile, Web, Desktop, Browser Extension, etc.).
Regardless of Vault Timeout settings, closing the Browser or Browser Tab will end your Web Vault or Browser Extension session, meaning you’ll be required to log in to access your Vault.
If you’re using a Browser Extension, you can bypass this by enabling the Unlock with PIN option and unchecking the Lock with master password on browser restart checkbox.
You can configure the following options from the Settings menu of any Bitwarden client application:
Vault Timeout (time-constraint)
Configuring this option will dictate how long Bitwarden can be inactive before timing-out. “Inactivity” is determined by the time since interacting with Bitwarden, not system idle time.
Each client application will have unique options (e.g. On System Idle, or On App Restart), however all applications include standard time-based options (e.g. 1 minute, 15 minutes, 1 hour).
Vault Timeout Action
Configuring this option will dictate what Bitwarden will do once the Vault Timeout time-constraint has lapsed. Bitwarden can either:
Locking your Vault will maintain Vault data on the device. You will only be prompted to enter your Master Password to decrypt your Vault, however no Two-step Login method will be required to unlock your Vault.
Bitwarden client applications don’t need to be online to unlock.
Due to the storage and reference of your decryption keys within the Web Vault, using the Browser refresh button on the Web Vault will cause it to lock.
Logging Out of your Vault completely removes all Vault data from your device, and will therefore require you to re-authenticate to access your Vault. You will be required to enter your Email Address, Master Password, and any enabled Two-step Login method in order to access your Vault.
Bitwarden client applications must be online to log in.
