Please also make sure to use strong, unique passwords for your site and do not share them with anyone. Do not repeat or transmit your password information in insecure plain text communication, such as email. As your site is on the public internet it's also under virtually constant assault and strong passwords and good hygiene help us keep it and your users safe from intrusion.
We recommend the use of a password manager like LastPass or KeePass. This software is free. You can also read more about how to generate a secure (and memorable) password here.
