If you would like to turn off 2FA, log in to your JetBrains account. Remember you will need to generate a one-time password or use a recovery code to login to your JetBrains Account when you have 2FA enabled.
Once logged in, click Your Account at the top of the page. Then click password.
Click Disable 2FA.
Here you will be asked to enter a one-time password which you can generate using the authenticator app you installed on your mobile device. Alternatively you can enter one of your recovery codes.
After doing so, 2FA will be switched off.
