Based on industry standards, we strongly recommend that you enable Multi-Factor Authentication. This is the most substantial level of Security for preventing password issues related to security. You can set password options from the Security settings screen to make your system as secure as possible.
For industry best practices, we recommend at least eight characters required for a password, at least one upper case letter, at least one numeric character, and at least one unique character. You can also enforce password changes after a certain amount of days from this screen.
