Jesus fuck. How many more authentication apps do we need that all do the same thing?
At work I need at least 4-5 different authentication apps because every customer has something different.
We don’t need another.
You only need one app, as long as the totp is implemented in a standardized way.
Microsoft products would like a chat...
I use my Microsoft account with a standard OTP app, you don't need their own app.
Wait until your workplace requires you to only use MS Authenticator push notifications 😭 and HOTP occasionally…
Is that a thing? Usually those have a fallback to a regular TOTP code.
I use Okta for work because we integrate SSO with it everywhere, but I could technically enter a code every time and swap out the Okta app for the other TOTP app I use.
My company is a MS shop, but they use TOTP as the second factor, and even that is optional. My department uses Okta, which is a completely separate system (we're a weird, separate unit entirely from most of the rest of the company).
I did too until it kept rejecting my tokens frequently - changing to M$ Authenticator "solved" it.
They must now require HOTP or something now. TOTP doesn't care what machine it's on, whereas HOTP does (well, you could spoof it if you really wanted).
They did. DUO was born.
They're probably using HOTP or something else, not TOTP. TOTP is literally just the key + any clock. Or maybe it's the "click button to authenticate" and not the "enter code to authenticate," which might not be HOTP or TOTP, but something else entirely (e.g. Steam's system is neither AFAIK).
If it's TOTP, you just need to get the key and can use any authenticator app.
4-5 TOTP apps? So far, when, e.g. Microsoft or Google have insisted use of their own Authenticator app is required, it’s worked fine for me using Ente Auth or similar just by entering the code / QR.
Yup, most 2FA is just TOTP, which is a pretty simple, open standard and is hardware independent. All you need is a key (the QR code or the numbers) and access to a reliable time source and you can make a TOTP app on anything.
I use Aegis on my phone and Authenticator on Linux (some GTK app), and they both produce identical codes for the same key.
This even works with some apps that hide the standard part - like Symantec VIP - it’s possible to extract what they are doing and use a standard TOTP app instead of VIP.
Random number generator 2fa?
