Copy 2FA from Android Messages von Daniel Rozenberg

This extremely simple Firefox extension copies anything that looks like a 2FA code from Android Messages to your clipboard, so you can stop switching tabs or manually typing the code before the notification disappears.

How do I use this?

Have Android Messages (https://messages.google.com/) open in a separate tab. Any time a 2FA message is received, it will be copied to the clipboard. Paste it where you need it.
