PASSKEYS: A NO-FRILLS EXPLAINER ON THE FUTURE OF PASSWORD-LESS AUTHENTICATION

Summary from the TLDR Design newsletter

Passkeys are beginning to make their way into popular apps, from password managers to multi-factor authenticators, vastly improving the user experience of authentication. There’s also a downside — having to store additional cryptographic keys for each login and every site for which you have a passkey often requires more space than storing a password. However, the security gains, the user experience from not having to remember a password, and the prevention of common phishing techniques more than offset the increased storage space.
