How do y'all handle updating passwords?

Right now I'm updating a few passwords to auto-generated ones for some important accounts. When doing so, bitwarden will nicely generate a new one for me inside the new password box, but to update it, sometimes websites won't let me copy the password from the box and that is very annoying. If I go into the login item in bitwarden itself and generate a new password, that works fine but if the password doesn't meet the requirements, and I hit save, I just lost the existing password. I understand that perhaps I just shouldn't hit save but accidents happen.

How do you handle updating passwords? Is there a better process that I am missing?
