This isn’t strictly a privacy question as a security one, so I’m asking this in the context of individuals, not organizations.
I currently use OTP 2FA everywhere I can, though some services I use support hardware security keys like the Yubikey. Getting a hardware key may be slightly more convenient since I wouldn’t need to type anything in but could just press a button, but there’s added risk with losing the key (I can easily backup OTP configs).
Do any of you use hardware security keys? If so, do you have a good argument in favor or against specific keys? (e.g. Yubikey, Nitrokey, etc)
I use vaultwarden (selfhosted bitwarden), which stores both passwords and OTP keys on my own server, which I backup regulary. This allows acces to my OTP keys from any device, as long as it’s in my local network or connected to my VPN.
Must say I really like this solution. If one of my devices fail, I have a pretymuch seamless switch to any of my other devices, which are already configured anyways, since it’s also my passwordmanager.
If the server fails, my phone, pc and laptop all still have the keys cached, so I can use those untill I’ve restored a backup.
Thats my configuration as well. I didnt think of the cache. Thanks for mentioning it.
I do think having the mfa on there is risky as you factually disable mfa with it imo. Its basically 2 passwords in the same place.
2nd issue: my vault has mfa as well for the admin account which I cant store in there for obvious reasons.
So in combination I‘ll probably use a second vault to store these to keep them seperate. Will check out aegis for this.
For the first issue thats not realy true. To access the totp key you still need the actual device with the key, it’s only now split over multiple devices. Like having multiple bank cards for the same account.
For the seccond issue: Thats a good point, I have not found a good solution for that either, unfortunately
