+|  Verification code  | `All(default)`/ `Email only` / `Phone only` | Select the sign-in methods available to the user. Choosing `All` , then both email and phone numbers can be verified for sign-in. Choosing `Email only` , then only eamil login is allowed. Choosing `Phone only`, then only the phone number is allowed to authenticate the login. |
+
+:::note
+
+For example, we want users to prioritize logging in with their email, and then consider logging in with a password if they can't use their email.
+
+:::
+
+First, we configure two login options, `Verification Code` and `Password`, and `Verification Code` is the first login option. Then we change the `verification code` rule to `Email only`, so that the user can only receive the login verification code by email.

+
+To make it easier for users to understand, we can change the display name of the `Verification code` login method so that users can easily understand that it is an email login.

+
+:::tip
+
+All sign-in methods will be added by default, it is required that at least one sign-in method be added.
