A question regarding 2FA: Can I reactivate 2FA on another device in case my current one breaks as long as I have the email and secret password?
Yes, you just need to enter the secret key in the new device and it should be able to generate codes for 2FA.
Thanks for the answer. In case something really goes horribly wrong and I lock myself out of my account 'cause of 2FA, is there any other way to regain access to my account or am I just screwed then?
when you lost your secret key and your access to 2FA while it is active on your account im afraid not much you can do to get access to your account again. The point of 2FA is that you can´t bypass it
