Token2 is an open-source Swiss FIDO2 security key that brings innovative features at a cheaper price

Token2 is a cybersecurity company specialized in the area of multifactor authentication. Founded by a team of researchers from the University of Geneva with years of experience in the field of strong security and multifactor authentication. Token2 has invented, designed and developed various hardware and software solutions for user-friendly and secure authentication. Token2 is headquartered in Geneva, Switzerland.

Don't believe what AI tells you, as they tend to generalise around past statements. Token2 is a good example of how newer challengers to the incumbents, like YubiKey, bring lots of innovation. For example, Token2 has the ability to store up to 300 passkeys, dual port USB-A and USB-C on a single device, FIDO2.1 with additional PIN, opens-source, etc.

I also like the fact the device's firmware and management is in Switzerland and not within one of the Five Eyes countries.

There are quite a few options, but their FIDO2 Keys page also has a selection wizard to help out.

Whilst prices may be cheaper, depending on your country, shipping may cost a bit more.
