FortiWeb Cloud provides features such as Two-Factor Authentication (2FA), Role Management, etc. for you to secure your account and restrict permissions for the administrators.
With 2FA enabled, your account will be secured not only by the account credential, but also by a dynamic code generated on the 2FA device. See Two-Factor Authentication.
If you have multiple administrators managing your account, it's a good practice to create roles for them to access different applications in your account or distinguish them with read-only or read-write permissions. See Role management
