Yes. Any applications using OAuth, the open-standard authorization protocol Reddit uses to authentic accounts, will be supported and you’ll be asked to enter your 6-digit verification code when signing in with your Reddit username and password.
However, some third-party applications may not be using OAuth and you may have trouble logging into them. In that case you can log into your third-party app by following these steps:
- While signing into the third-party app, enter your Reddit username as you normally would.
- In the password field, enter your password and your verification code using the format <password>:<verification_code>. (Don’t forget the colon in the middle. If you do it won’t work).
If you have more questions that aren’t covered in these FAQs, check out r/help. Someone may have had the same question, or you can ask a new one and a Reddit administrator or one of your fellow redditors will help you out.
