My bank tried to add typing heuristics on the password box years ago. It wouldn’t lock you out, but you had to go through extra verification steps if you failed. I failed the test pretty much every time I logged in, and I’m sure it happened a lot because 6 months later it was gone. In that use case it was an extra attempt at locking down bank access, which I can appreciate, but I hated that it was wrong most of the time.

Our API returns a signature detection percentage. We recommend our users to accept users with a signature accuracy score of over 80%.

What does this means? When you type in the morning or late at night you have a different typing pattern. When you are tired or drunk, you have a different keystroke pattern, but still, our algorithm is able to identify you. You won't have a 90% matching score, but you will still have over 80% signature matching score.

This is why Typing AI's algorithm is better than our competitors.
