- Jennifer Berlin
- Great and easy-to-use extension. 2 factor codes are right there! Paid for premium to get the private backup feature.
- Rachel Finn
- Really happy with this extension. Has been easy to use and it’s so much nicer having my codes on my laptop instead of constantly grabbing my phone. I paid for the premium features so I could back up my codes and it was worth it for the peace of mind.
- Sean Emerson
- 3 stars as on the free version seems I cant edit or remove an entry. not much use on the free tier. Should be a paid only plugin or add at least the basic functionality to the free version.

- While it works really well, it becomes slowly out of sync with time. I've had this running for a few months now on an AWS workspace and I have to wait for it to click over to the next number before actually entering the auth code into openVPN. When using the microsoft phone authenticator app it never goes out of sync. Not sure how to reset the timer because I really don't want to set up all my accounts in this authenticator again.
