This screenshot was taken from a test email sent to a Gmail account, so it gives the option to sign in with a google account or request a one - time passcode.
Cafodd y ciplun hwn ei dynnu o e-bost prawf a anfonwyd i gyfrif Gmail, felly mae'n rhoi'r opsiwn i fewngofnodi drwy gyfrif google neu ofyn am gyfrinair y gellir dim ond ei ddefnyddio unwaith.
