When your device requests an IP it sends over a significant amount of data. DHCP fingerprinting is very similar to browser fingerprinting but unlike...

Bitwarden has a FOSS client app and FOSS server apps exist (though the default service is not FOSS).

Syncing 2FA keys brings the danger with it that you accidentally sync the key to the device that is used for the first factor thus making it not 2FA anymore.

That is what i meant. It is OSS but not FOSS because you need a key to start it.
