@Rubicon #2FA should ALWAYS be free of charge and without any mobile number. I refuse to enter it e.g. for #TwitchTV because I know they want to collect our mobile numbers with this. I don't like it how my credit card provider has implemented it that way. #TOTP is the most secure one, you can use any program/app for this. I have written a small wrapper Shell script for #oathtool to make it easier: 2fa.sh friendica instead of oathtool --base32 --totp <secret-key>. If you want to review it: https://f.haeder.net/2fa.sh
