What limits are set in Plesk for username/password length?
Usernames and passwords in Plesk are case-sensitive. The following limits for username and password length exist:
- Plesk user name length: from 1 to 20 symbols;
- Plesk user password length: from 5 to 255 symbols;
- System user name length: from 1 to 16 symbols;
- System user password length: from 5 to 255 symbols.
These limits are hard-coded, which means they cannot be changed in Plesk configuration. Remember that system limits have a higher priority than limits configured in Plesk.
