I had this happen last week - and recovered.

I use Firefox and Chrome browsers, for different functions and for common ones - on two computers. That's 4 browsers. I have various indispensable addons like Session Managers, Password Managers and syncing set up so that I only have to be concerned one set of data, or 2 if it won't sync between Firefox and Chrome.

I'd never had to recover a password so I Googled how to look it up under my password manager. It told me where to look. I found it and copied it over to the other browser.

Easy peezy - IF you have a password manager and haven't saved over it with an "updated" incorrect password.

I really hope this helps you. I love your YouTube work.
