On BikiniFanatics we have a security in place that prevents the abuse of accounts. This means that you can't use more than 3 devices per account.
If an account seems compromised it automatically locks it and forces you to reset your password. Simply follow the steps that are shown on the login form. Or reset your password here!
Make sure to check your email inbox since that's where you'll be notified in the case of a lock and how to regain access.
