Do I Need to Change My Password Periodically?

For your account security purposes, you are advised to change your password periodically, regardless of whether your account is created by yourself or another user.

By default, the validity period of a password is 90 days. Ten days before a password expires, the system prompts you to change the password upon your login. If you have linked an email address to your account, the system also sends a password expiration notification email to you every day until you change the password.
