You can set up your browser to do this automatically, but this is just one step in becoming clean. You need to make sure that there’s nothing installed on your devices that might be fishy. Keylogger, trojans, viruses etc.

If you still suspect things to be strange. Clean reinstall!

Best practice would be to use 2FA where possible. Generate passwords as complex as possible and use a password manager yourself to keep track of everything.

If possible, use unique user/pw where possible.

Don’t install crap on your devices, log out, clean cookies/cache etc.
