You can set Access Control Lists (ACLs) to limit logins to your account from pre-approved IP addresses, host masks, and networks.
This can protect your account in the event of your login credentials being compromised.
ACLs can take multiple parameters of the type:
- Exact IP address
- Netblock (i.e 205.210.42.0/24)
- Hostname mask: (i.e hostmask:*.rogers.com)
- Regex (posix regular expression) (i.e regex: [A-Z]modemd.bell.ca)
ACLs can be further controlled via your 2-factor authentication settings, where you can specify that login from outside your ACLs can be validated with 2FA.
