+# Reset Password Flow
+This gem supports two different ways to reset a password on a resource. Each password reset flow has it's own set of
+operations and this document will explain in more detail how to use each.
+The first and most recently implemented flow is preferred as it requires less steps and doesn't require a mutation
+to return a redirect on the response. Flow 2 might be deprecated in the future.
+
+## Flow #1 (Preferred)
+This flow only has two steps. Each step name refers to the operation name you can use in the mount options to skip or override.
+
+### 1. send_password_reset_with_token
+This operation on the gem will send an email to the specified address if it's found on the system. Returns an error if the email is not found. Here's an example assuming the resource used
+for authentication is `User`:
+```graphql
+mutation {
+  userSendPasswordResetWithToken(
+    email:       "[email protected]",
+    redirectUrl: "https://google.com"
+  ) {
+    message
+  }
+}
+```
+The email will contain a link to the `redirectUrl` (https://google.com in the example) and append a `reset_password_token` query param. This is the token you will
+need to use in the next step in order to reset the password.
+
+### 2. update_password_with_token
+This mutation uses the token sent on the email to find the resource you are trying to recover.
+All you have to do is send a valid token together with the new password and password confirmation.
+Here's an example assuming the resource used for authentication is `User`:
+
+```graphql
+mutation {
+  userUpdatePasswordWithToken(
+    resetPasswordToken: "token_here",
+    password: "password123",
+    passwordConfirmation: "password123"
+  ) {
+    authenticatable { email }
+    credentials { accessToken }
+  }
+}
+```
+The mutation has two fields:
+1. `authenticatable`: Just like other mutations, returns the actual resource you just recover the password for.
+1. `credentials`: This is a nullable field. It will only return credentials as if you had just logged
+in into the app if you explicitly say so by overriding the mutation. The docs have more detail
+on how to extend the default behavior of mutations, but
+[here](https://github.com/graphql-devise/graphql_devise/blob/8c7c8a5ff1b35fb026e4c9499c70dc5f90b9187a/spec/dummy/app/graphql/mutations/reset_admin_password_with_token.rb)
+you can find an example mutation on what needs to be done in order for the mutation to return
+credentials after updating the password.
