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?
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!
FWIW if you use Aegis, that app will show you the QR codes after the fact.
Authenticator Pro is awesome, FOSS, and allows you to backup your 2FA.
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
Aegis or Ente Auth for Android. Backup your databases in your cloud of choice. Do not use Google Authenticator.
Keepass + Syncthing
KeepassDX is a good android client, and it supports TOTP.
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.
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.
I use 1pass at work and vailtwarden personally. Both are perfect solutions.
Im using bitwarden free for passwords only. I might try vaultwarden
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
Just transfer them to another device? Or save the big QR code it generates as an image.
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?
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.
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.
I was afraid of using keypassxc since I dont trust myself, but using it as a backup sounds like amazing solution. Thank you
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.
You could use a python script with oathtool copied onto each of your devices. This is not a good suggestion.
