I already lost around countless accounts at this forum because of this 2fa shit so I need a proper 2026 guide.
first, put in a pgp public key (it's top right corner, hover over ur username then click Account > scroll down a bit > pgp key) and verify it. then u can enable 2FA by just clicking on the dropdown above pgp key, and selecting Enabled. now, every time u log in it will give u a pgp message encrypted with ur key, decrypt it then put in the verification code it gives u. hope that helps
