For professional or advanced use, YubiKey remains the most comprehensive option.

Frequently Asked Questions: YubiKey vs Google Titan
Does Google Titan work with non-Google services?
Yes. As it is FIDO2 certified, it works with any compatible service — GitHub, Dropbox, Microsoft, Facebook, Coinbase, and many more. It is not limited to Google.
Why does YubiKey store fewer passkeys than the Titan?
The YubiKey 5 series stores up to 25 passkeys. Google has prioritised massive storage (up to 250). For most users, 25 is enough, but for power users, the Titan has the advantage.
Can I use Google Titan with an iPhone?
Yes, via NFC. Simply tap the key to your iPhone to authenticate — it works just like the YubiKey NFC on iOS 13.3 or later.
Do I need two security keys?
It is strongly recommended to have a second backup key registered. If you lose the primary one, the second allows you to access your accounts. You can easily combine a YubiKey and a Titan.
YubiKey for pro use, Google Titan for personal Google use
If you primarily use Google services and only need FIDO2, the Titan is a solid choice. If you require OTP, PIV, OpenPGP, or extensive corporate compatibility, YubiKey 5 NFC is the only viable option.
In both cases, these keys offer identical and foolproof protection against phishing. The decision comes down to the extra protocols and your preferred ecosystem.
