Forgotten you password and can't log in? (It should be in your KeepassXC Password safe!)
Do not worry because resetting your password is easy.
Simply go to the login page, select the "Reset your password" tab and follow the instructions!
SECURITY: Always use a long (>23 chars) and random password with upper and lower case letters, digits and other characters, generated by and kept in a password safe such as KeepassXC (Don't download it from any other site).
