User Account Requirements
From OpenCms Wiki
Here are the requirements for creating an user account in OpenCMS (tested with 6.2.3).
- Username is required
- Minimum required length is 1 character.
- Valid characters are only letters, digits and "-._~$@".
- Email addresses can be used as the username (but strongly discouraged!)
- There is no way to change the username once a user account has been created within OpenCMS. Since email addresses are prone to changing it causes them to be bad candidates as usernames in the long run.
- Password is required
- Minimum required length is 4 characters.
- First name is required
- Minimum required length is 1 character.
- Last name is required
- Minimum required length is 1 character.
- Email address is required
- Must validate as an email address (Uses commons-validator)
