Acidently turned off 2FA on a computer. How do I turn it back on

I had 2FA for Bitwarden turned. I accidently told Bitwarden not to require 2FA on my laptop. Now of course, it never asks for my code from the authentication device.

I actually want to require use of the authentication device EVERY time I log into Bitwarden after I have logged off. If it is locked, No device is needed. But I always logoff of Bitwarden at the end of the day. And I want to require use of the device to logon again the next day.

How do I tell Bitwarden to ignore my past instructions about my laptop being a safe computer, and require it to demand the authentication device when I logon?

… just quick re-questions for clarification so that someone can help you better:

What do you mean by “it”?

Do you mean the Bitwarden web vault?
Do you mean the Bitwarden desktop app?
Do you mean the/a Bitwarden browser extension? If yes: with which browser?

Which OS do you have on your laptop? Windows? Chrome OS? MacOS? Linux? …?

I have no specific idea for your problem though - but would first think of deleting cache, deleting stored info (/your “remembered device”) in your browser about the Bitwarden vault (still not sure what you meant by “it”), deinstalling and (after reboot) reinstalling the desktop app or extension or something like that…

(PS: from my last sentences: please don’t try everything - as I wrote, it would help to know more about “it” / your browser / your OS to be more specific…)
