Nice idea and the theory behind it is also a bit older and proven. But how does it work with users who want to log in via smartphone and PC, or tablet? Because the way of typing is different on each device. You would then have to think of ways to link different profiles.

If you integrate TypingDNA Verify and the end-user tries to authenticate from a phone, it will go by default on SMS (the fall-back option we added using Twillo).

Alternatively, you can use TypingDNA's API. This will work on any device type (smartphones, computers, tablets, etc.).

In summary, TypingDNA Verify works on phones as well, but it will just go directly to SMS rather than typing biometrics.

I hope this answers your question, [Jörn](https://hashnode.com/@sign9)
