Is it possible to stay logged into Bitwarden after closing down the browser? (in my case Opera)
Yes, this is possible. However, it is insecure as the vault will be written to computer’s disk, which could be targeted by malware (theoretically).
To do so, open Bitwarden browser plugin and choose Settings, then check “Security” column. You can choose option “Never”.
Where is the vault written to disk? Is it still encrypted once written to disk?
