- Open the Threads app and move to your profile.
- Tap on the menu icon in the top-right corner.
- Next, go to Account -> Security. This will take you to the Meta Account Center.
- Here, tap on Two-factor authentication.
- Now, choose your Instagram account. As Threads uses your Instagram account as the identifier, you will need to enable 2FA for your Instagram account and that will enable two-factor authentication for Threads too.
- Here, choose one of the security methods. Here, I have selected SMS as it’s easier to set up, but you can also use an authentication app or WhatsApp for extra security.
- Now, enter the one-time PIN you receive on your phone number.
- And you are done. Two-factor authentication is now enabled on Threads and Instagram too.
- I will also strongly recommend generating backup codes in case you lose access to your phone number. Tap on “Additional methods“.
- Now, select the “Backup codes” option.
- Save the backup codes to a safe location. In case you don’t have access to any of the authentication methods, you can use one of these codes to sign into your Threads or Instagram account.
Besides that, you can learn how to delete or deactivate your Threads account in case you had enough of the new social media app. Apart from that, you can also change your Threads username, and we have a dedicated guide for you.
