Check to make sure you are using the correct login credentials you provided when you created your account. If you have forgotten your password, you can reset by clicking here. Alternatively, there could be a security related reason why you are unable to log in:
1) If we cannot validate your user credentials, our security system may prevent access until your information is verified.
2) If your account is suspended, you will not be able to log in until the reason for the suspension is resolved.
You can contact us by email at support@clipkard.com for assistance with any login issues.
