But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.
I broke down how passkeys work, their strengths, and what’s still missing

Saved to Bitwarden fine on my desktop browser. When I try to log in with a browser on my phone, it asks for my username and does nothing more after that dialog closes.
