Two-factor authentication (2FA) is a vital security step that protects your accounts by requiring both a password and a second verification method, such as a one-time code, security question, or physical key. While 2FA keeps hackers out, it can sometimes lock you out of your own accounts if you lose access to that second step — for example, if you change phones or numbers, delete an authenticator app, or misplace a security key.

The experts at TelephoneSystems.Cloud  explain why this happens and share practical steps on how to avoid getting locked out and what to do if it happens, so you can keep your accounts secure and accessible.

Juliet Moran, tech expert at TelephoneSystems.Cloud said: “Two-factor authentication is a standard practice these days in keeping accounts secure.

“If a hacker has access to your passwords, the second security step is often what saves people from having their personal information compromised. However, users can find themselves locked out of their own accounts if they lose access to that second verification step.

“Setting up back up options, storing recovery codes securely and updating authentication settings when you change phones are important steps to take to ensure you always have access to your account.”

How to regain access and prevent 2FA lockouts:

Set up a back up authentication method

Some services allow you to have another authentication method so that if your primary 2FA fails, there is a back up. You may be able to log in using a SMS code or verification email. If you get the chance to set up a back up authentication method, use it.

Store back up and recovery codes

Platforms may provide you with a unique code when you originally set up your two-factor authentication. This code can be used once to gain access to the account if the primary 2FA method does not work. Keep these codes safe and secure and store them offline in case you need them to access your account.

Restore or transfer your authenticator app

If you use authenticator apps such as Google Authenticator you can sometimes restore your 2FA settings through a backup when transferring data to a new device. To do this you’ll need to set up app backups ahead of time. This can come in handy if you change your phone or if it gets lost, damaged or stolen.

Contact account support

If you’re having issues with your second authentication step and can’t gain access to your account, you may need to contact account support. Depending on the service the process may be lengthy and It’s likely you’ll have to provide information to verify your identity.

Take preventative measures to avoid future lockouts

To minimise the risk of being locked out again, take preventative measures. Store recovery codes securely, add a secondary phone number or 2FA method and regularly review your settings and backups.
