Configuring the Forgotten Username Feature

Log in to the AM console as the administrator.

Navigate to Realms > Realm Name > Services and select the User Self-Service service.

Select the Forgotten Password tab.

Enable Forgotten Username.

Enable Captcha to turn on the Google reCAPTCHA plugin. Make sure you configured the plugin as described in "Configuring the Google reCAPTCHA Plugin".

Enable Security Questions to display security questions to the user during the forgotten password reset process. The user must have security questions defined in their profile, and must correctly answer the presented questions to be able to reset passwords.

Enable Email Username for the user to receive the retrieved username by email.

Enable Show Username for the user to see their retrieved username on the browser.

In the Token LifeTime field, enter an appropriate number of seconds for the token lifetime. If the token lifetime expires before the user resets their password, then the user will need to restart the forgotten password process over again.

Default: 300 seconds.

To customize the Forgotten Username outgoing email, perform the following steps:

1. In the Outgoing Email Subject field, enter the subject line of the email.

   The syntax is lang|subject-text, where lang is the ISO 639 language code, such as en for English, fr for French, and others. For example, the subject line value could be: en|Forgotten username email.

2. In the Outgoing Email Body field, enter the text of the email.

   The syntax is lang|email-text, where lang is the ISO 639 language code. Note that email body text must be all on one line and can contain any HTML tags within the body of the text.

   For example, the email body text could be: en|Thank you for your inquiry! Your username is %username%.
