OAuth Login

How OAuth and external sign-in providers work with Amerencio.

OAuth Login

Amerencio supports login through Amerencio itself and external providers such as Google, Microsoft, Discord, GitHub, and Facebook.

User flow

1. The user starts sign-in.
2. Amerencio verifies the provider and configuration.
3. The user completes provider authentication.
4. Amerencio links or resolves the provider identity.
5. Amerencio still applies its own account rules, including email verification and anti-abuse checks when required.

Provider identity

Provider sign-in is matched by provider identity id. Do not rely only on provider email, because provider email can change or differ from the Amerencio account email.

Integration advice

Use Amerencio routes and supported SDK examples instead of building your own provider callbacks unless your integration has a specific backend requirement.
