How to change the vault timeout

In the Chrome extension bitwarden’s settings I set the vault timeout to 4 hours. But when I close the Chrome I’m logged out of the browser extension.

Where can be set that 4 hours of logging into browser extension will remain no matter if I close the browser or restart the computer?

This is not possible.

Hey there, please note: Vault Timeout Options | Bitwarden Help Center

Due to the web vault and browser extension depending on your web browser, there are unique “timeout” scenarios to consider:

  1. If you refresh your browser (CMD/CTRL + R), your web vault will lock. Refreshing will not affect a browser extension.
  2. If you close your browser tab, you will be logged out of your web vault. Closing a single tab will not affect a browser extension.
  3. If you quit your browser, you will be logged out of both your web vault and browser extension.
