title: Build a custom flow for resetting a user's password description: Learn how to build a custom flow using Clerk's API to reset a user's password.

<Include src="_partials/custom-flows-callout" />

The password reset flow works as follows:

1. Users can have an email address or phone number, or both. The user enters their email address or phone number and asks for a password reset code.
2. Clerk sends an email or SMS to the user, containing a code.
3. The user enters the code and a new password.
4. Clerk verifies the code, and if successful, updates the user's password and signs them in.

This guide demonstrates how to use Clerk's API to build a custom flow for resetting a user's password. It covers the following scenarios:

• The user has an email address as an identifier
• The user has a phone number as an identifier

Email address

Prompting users to reset compromised passwords during sign-in

If you have enabled rejection of compromised passwords also on sign-in, then it is possible for the sign-in attempt to be rejected with the form_password_pwned error code.

In this case, you can prompt the user to reset their password using the exact same logic detailed in the previous section.

Phone number
