Two factor authentication is great and very necessary, I enable it in most places where it is available.
The one downside is that when you lose access to your phone you need to reset 2FA in a lot of places. And obviously the backup codes also always seem to get lost.
BTW: This is a message to Matthew who I hope can help met get access again to my Matrix Mastodon account that I have access to this domain and the e-mail I sent him wasn’t spoofed! 😉
