🇯🇵 Password Reuse in Japan: still at 84% [2026]
The FIDO Alliance measures a 93 percent success rate for passkey sign-ins, so why does adoption sit between 5 and 15 percent after launch? Because more than 80 percent of passkey failures happen on the device and never reach your server.
A passkey prompt is an OS modal, so a user who cancels it or lets the biometric time out generates no request at all, which means your logs look clean while the login quietly dies.
One banking app lost 30 percent of its passkey attempts after iOS 18.2 changed how Safari shows the autofill dropdown, and the backend reported fewer requests with zero errors. Another team traced a 15 percent bounce rate to a 1Password extension covering the native autofill, and a travel site found that 92 percent of its unexplained Firefox errors were Bitwarden getting in the way.
The post walks through the client-side events worth capturing, the WebAuthn error codes that map to an actual fix and the device combinations where you are better off turning passkeys off. If a Galaxy A14 succeeds 15 percent of the time while everything else clears 92, how long before anyone notices?
Trend Micro asked 1,034 people in Japan how they handle logins and 84.3 percent still reuse passwords, which is roughly where the number sat back in 2023. Only 10.8 percent use a password manager, while 40.9 percent memorize their passwords and 34.3 percent keep them on paper.
The easy read is that nobody cares about security and the survey kills that on the next page: 91.1 percent have heard of passkeys and among people who actually use a service that offers them, 87.7 percent have switched. So the bottleneck is not the user, it is the login screen in front of them.
What pulls people over is convenience rather than safety, with 41.8 percent naming ease of use against 19.6 percent naming security, and a provider simply recommending it moves another 32.3 percent. The two worries holding the rest back are losing access after a phone change and getting locked out, both a little above 35 percent, which are documentation problems more than technical ones. If nine out of ten of your users already know what a passkey is, what is your rollout waiting for?
