Account Switching
Did you know that you can have up to five Bitwarden accounts logged-in at the same time with the Bitwarden desktop and mobile apps? Using account switching, seamlessly switch between Bitwarden accounts such as personal and work accounts.
To log in to a second (or third, or fourth, or fifth) account, select the currently logged-in account from the top menu bar and select Add Account.

Selecting Add Account will take you to the login screen:

tip
If you have accounts on multiple servers, for example if an employer who self-hosts Bitwarden has issued you a families organization sponsorship, use the server selector drop down that is located on the login screen and select the Self-hosted menu to change the Server URL to the URL for the account.

In this example, your work account may use something such as https://your.company.bitwarden.com
and your families organization account would use https://vault.bitwarden.com
.
Once you log in to your second account, you can quickly switch between them from the same menu, which will also show the current status of each account's vault (locked or unlocked). If you log out of one of these accounts, it will be removed from the list unless vault timeout is set to log out.
備考
Most vault actions, including adding new items or folders, syncing, and settings such as vault timeout and unlock (PIN or biometrics) will only apply to the active account, which you can determine by the icon displayed in the top menu bar of the app.
Some options such as theme are applied to all accounts.
Auto-fill
