ISPConfig + Roundcube and lost password

I've found this thread from ~3 years ago.
https://www.howtoforge.com/communit...a-forgot-password-on-roundcube-webmail.70860/
But how can I implement something to users that don't have access to ISPConfig panel to reset their password in case they forget?
Do anyone have a clue about it?
Cheers!

 

Use Internet search engines with

Code:

That's not an answer, but thanks.
