I'm trying to move away from Authy since they're ending support for their desktop app, and I thought Aegis would be the right app for me to jump to, but it doesn't seem to have a desktop app. So I'm wondering what FOSS apps the rest of you use for Desktop and Mobile 2FA?

Slightly off topic but desktop 2FA apps kind of kill the point of 2FA.

2FA protects you by ensuring that even if your computer is compromised your account will have a layer of protection in that second factor “aka something you have”.

If you have that on your desktop, you might as well not have it.

If you find 2FA off of your desktop annoying I recommend looking into passkeys. Open standard and less annoying. Just not well supported.

Passkey is on your device though?

It doesn’t kill the point of 2fa. It’s something you have… you have your device. If you didn’t you wouldn’t have the TOTP code.

The something you know (password) is much more likely to be breached and stolen. That is what isn’t tied to your device. You probably want the second factor to be linked to just the devices you have.

Edit: I was wrong and mixed up passkeys with something else. Passkeys I think are still better than desktop totp apps because at least they work with secure hardware on the platform.

That’s not what passkeys are in many implementations. Look up Google/microsoft/apple passkeys. That’s what people mean when they say passkeys.

You’re thinking of a device like a Yubikey, which is a great device.

[–] mholiv 1 points 10 months ago

You’re right. Yah. Still at least those use “secure element” equivalents at least.

I've seen people say this, but what makes your phone so much safer than your computer?

[–] mholiv 2 points 10 months ago

It’s the second factor that adds security. Aka “something you have”.

If you use totp on your phone to log into an app on your phone yah it’s true it’s not much more secure (although I would argue app isolation does make it more secure) but using your phone to provide totp for your desktop proves that second factor.

Where do you keep your TOTP if not on your devices? Or do you own a separate device exclusively for TOTP?

[–] mholiv -1 points 10 months ago

For less important things I keep my TOTP credentials on my phone. Not perfect but definitely safer than a PC statistically speaking.

For more important things I use either a passkey or yubikey or a gpgsmart card depending on what is supported. All three work via usb or NFC.
