Nostr login is the best method.
As backup use a LN-auth from a dedicated LN wallet but not a custodial!
If the custodial is closing your access you lose login to SN.

Why people rely so much on these custodial when it cost you nothing to create a nostr account or run a proper LN wallet?

Custodial accounts must be used only temporary, as decoy, as testing or specific one-time use. Not for long time and be dependale.
Custodial = disposable
