Message templates - Amazon Cognito

Message templates

You can use message templates to insert fields into your messages using placeholders that the corresponding values replace.

Template placeholders

Description

Token

Verification code {####}
Temporary password {####}
User name {username}
Note

You can't use the {username} placeholder in verification email messages. You can use the {username} placeholder in invitation email messages that you generate with the AdminCreateUser operation. These invitation email messages use two placeholders: the user name, as {username}, and the temporary password, as {####}.

You can use advanced security template placeholders to do the following:

  • Include specific details about an event such as IP address, city, country, sign-in time, and device name. Amazon Cognito advanced security features can analyze these details.

  • Verify whether a one-click link is valid.

  • Use event ID, feedback token, and user name to build your own one-click link.

Note

To generate one-clink links and use the {one-click-link-valid} and {one-click-link-invalid} placeholders in advanced security email templates, you must already have a domain configured for your user pool.
