I switched to Bitwarden password manager and got on a 2FA activation spree. For general sites https://twofactorauth.org/ was really helpful to see which sites do support 2FA.

I would like this thread become a similar resource for torrent trackers.

These trackers do support 2FA:

BeyondHD [BHD]
CinemaZ [CZ]
Empornium [EMP]
Nostalgic
Orpheus [OPS]

These trackers have/had problems with 2FA, see their forums if the problems still exists:

DXDHD [DXD]

Please add more trackers if you know any!
