Authenticator 2FA | Sentinel 4+

Great help, design and seamless syncing between devices

I have experience with a couple different 2FA applications. Most notably LastPass Authenticator, DUO (for work), Google and even Authy. Obsidian offers a couple things most off these apps lack, and that's syncing between devices. Now, Authy tends to do the same thing but stores your 2FA's on their servers which I do have security concerns about. Obsidian does this trough the iCloud Keychain so it will even work when you're not logged in. I encountered some problems with the syncing at first but got great help once I emailed the developer. Once everything ran smoothly, I was able to just enjoy the clean design of the application. The dark mode that comes with the free version looks so minimal and offers a way better feel than all other Authenticators out there! I would recommend this app to anyone who loves well thought out apps, security and is looking for an authenticator that syncs between your Mac and your iPhone without you worrying about it.

Great app, but can easily extract secrets

Although I like the app, particularly the synchronization among devices and the clean overview of OTP codes, it is easy to extract the secrets for the different codes from the app (and to copy them over to another app/device). Perhaps the security of the app could be improved by forcing an authentication when editing an accounts.. Apart from that, very neat app, well done!

Developer Response ,

Hello Frank!

Thanks for the feedback!

Honest reply: if we didn’t allow to export secrets someone would have complained saying “we force a lock-in not allowing users to move to another app”.

We are for a free world and against lock-in.
We want our users to use our app because they feel safe and at home with us, not because we coerced them.

That’s why we added that feature.
I’m sorry you interpreted it as “less secure”, it was not our intention to make you feel that way.

It just works

Absolutely love this app. I have been using it on my phone, laptop and desktop and has been working flawlessly ever since I started using it. If you care about security and ease of use: go get this app. It just works.
