So basically what title says.
Im using 2FA with google authenticator for multiple accounts. What if my phone gets stolen? Can I have some kind of backup? Or maybe sync with some self hosted service?
Bonus question: what 2FA should I use instead of google?
Use Aegis on android or 2FAS on iOS. And just backup your seed on hdd/usb stick. Dont upload on cloud.
Thx, looks perfect!
IOS has a 2FA feature included in the key chain (passwords) settings. No need for a third party app. If you backup passwords via icloud, you are already set.
Never upload your passwords to any cloud. Always use good foss instead of proprietary software.
There are many forms of 2FA. I’m guessing you mean TOTPsoh you actually wrote that, my bad lol.I copy the keys from Aegis to KeePassXC. KeyPassXC’s database is part of my regular backup. This way I have two apps generating the same TOTPs.
I was afraid of using keypassxc since I dont trust myself, but using it as a backup sounds like amazing solution. Thank you
Personally I recommend just using KeePassXC and a KeePass app (I use KeePassium on iPhone).
You always have access to all your data that way. No company is monitoring you. A lot of apps make it very difficult to backup!
My totp database is in the cloud for syncing but needs a key file I don’t keep in the cloud (and a password). My passwords are entirely separate.
Thank you all for tips. I got Aegis and backing it up to my selfhosted nextcloud. I will also keep google app in use for now, but I might get keypassxc or vaultwarden in the future
Cheers
As a user of Nextcloud, Aegis, and Vaultwarden, I can say it’s a great set of tools. I don’t know how I ever got by without Bitwarden/Vaultwarden.
Aegis is a free open source TOTP 2FA app like Google Authenticator, and available on both F-Droid and Google Play. You should be able to export from Google Authenticator and import into Aegis.
Edit: I had assumed because Aegis had an option to import from Google Authenticator that this would mean you could export in bulk. Bad assumption to make, it sounds like you can do it if you have a rooted phone but Authenticator doesn’t make it easy. I did find this that shows a method to do a handful at once: https://blog.jay2k1.com/2021/11/17/how-to-bulk-migrate-from-google-authenticator-to-aegis/
Most comments recommend aegis, Im installing it right now. Thx

If there is a way, I was unable to find it
Yes, I just did it. Go to google auth - transfer accounts - you get QR code, screenshot it - and import in Aegis
Huh. I was not able to make it work, perhaps I just overlooked something.

What’s the benefit of Aegis over FreeOTP+?
For one, Aegis is more well known. Aegis has 6k+ stars where FreeOTP+ has about 500. This doesn’t mean it’s better, just that people are more likely to recommend it.
Aegis also has more features, and can import from many different authenticator apps (though as many don’t allow exports, this may require technical knowledge to get the database and feed it in). If you have root then Aegis can pull directly from the other apps.
Aegis claims they are better than FreeOTP because the encrypt passwords at rest.
One big difference is FreeOTP+ lets you not have to enter a pin/password to see the codes while Aegis you need to enter a pin, password, or biometric to see your codes.
Popularity aside, you sold me on the import compatibility. FreeOTP+ can export to other FreeOTP+ installations, but I’ve had issues with exporting to other apps. I had to manually import using the secrets displayed within FreeOTP+. The encryption sold me. I will be migrating to Aegis. I haven’t heard of it until this post, and have been using FreeOTP+ sans encryption.
I use Authy and am logged in on multiple devices so if I lose my phone I can still access the 2FA on my laptop. Then log back into the new phone using the laptop.
I use Authenticator Pro. It allows backups for itself or for exporting to other apps.
+1 To AuthPro, the guy behind the app is really cool
I use Aegis like several others here and then backup my codes to a Cryptomator vault which I can then sync online for cloud backup
Aegis or Ente Auth for Android. Backup your databases in your cloud of choice. Do not use Google Authenticator.
All you need is the TOTP secret, and it will generate OTPs. If you enter the secret in another TOTP app, you’ll also get OTPs. Here’s a Ruby lib that will render OTPs from a secret, for example: https://github.com/mdp/rotp
For an Android TOTP tool, I like FreeOTP+. You can even use it for Steam OTPs.
Authenticator Pro is awesome, FOSS, and allows you to backup your 2FA.
Use Aegis lol.
This, I’ve just installed it this week and I think it’s better than Google (though I’m suspicious of the “free” service.
Its not a service its an app. And yes nothing is free so please donate to the Devs
Keepass + Syncthing
KeepassDX is a good android client, and it supports TOTP.
I prefer an authentication code, which I can save on a pendrive or, if not, a second email. I never use 2FA with a phone number, precisely because a phone is never secure and is also a privacy hole. It’s enough that they know my email, it’s not necessary that they also know my phone number.
Who knows my phone number if I use Aegis?
When enrolling with the 2FA take a screenshot of the QR code, print it and add it to wherever you keep your secure documents. The QR code is your private key, just scan it again to add a new device if you lose your original.
Obviously you need to keep the code secure!

Just transfer them to another device? Or save the big QR code it generates as an image.
