With the Bitwarden browser extension in a desktop browser, by default the timeout period to lock the vault is upon browser restart. I consider this quite non-secure because many people leave their browsers open almost all the time, resulting in the vault rarely getting locked. I would like to suggest changing the default to something more secure, such as one hour. I have only tested this with Firefox on Windows 10, so I don’t know if the default timeout is different in different browsers’ extensions.
@wolpret Welcome to the forum!
I just changed the title of your request, to make more clear what you are requesting (your original title was: “Browser extension vault timeout period”).
