Please note that, once customers have migrated to GOV.UK One Login, Government Gateway will no longer be available therefore customers’ online accounts will only be accessible via GOV.UK One Login.
Sylwer, unwaith y bydd cwsmeriaid wedi mudo i GOV.UK One Login, ni fydd Porth y Llywodraeth ar gael mwyach felly dim ond trwy GOV.UK One Login y bydd cyfrifon ar-lein cwsmeriaid ar gael.
