How to allow password reset for non-conforming usernames

Subscription Manager uses a certain format for assigning usernames which includes company names as well. In order to provide seamless migration of Identity services from Action Hub to Subscription Manager it might be desirable to keep existing usernames.

This is achievable, however; a potential problem could be that the username may not be validated at Forgotten password page:

To avoid this problem, find and remove the following texts from ~\App\dist\register.js

<dxi-validation-rule type="pattern" pattern="^([A-Za-z0-9_.-]+)@([dA-Za-z0-9.-]+).onxmpro+.com$" 
message="The username you entered is not valid. Please check your typing and try again."> 
</dxi-validation-rule>
