# Sign-in Methods

Users can sign-in using one of three methods:&#x20;

* **Credential:** An email and a password set by the user that adheres to [NIST guidelines](https://clerk.com/docs/security/password-protection), including enforcing character limits and ensuring that the password isn't compromised in prior breaches
* **Social Providers:** Abbey currently supports Social Login via Google, Github, or Microsoft.&#x20;
* **Magic Link:** A user will get a link to sign-in via their email with a verification code, creating a fully passwordless experience.&#x20;
