TypingDNA Authenticator - 2FA codes in your browser, secured by the way you type

What if your credentials are stolen and a malicious website records the way you type?

would your typing pattern change when you use different keyboards?

Interesting and terrifying as properly stated by @rrhoover! Perhaps a stupid question, but it just came! It looks like to gain access to the authenticator, you still need to provide an ID and password, which is tracked when typing to identify your typing pattern, right? That said, it looks to me like a "password manager" for second-factor authentication. In that sense, using mobile apps (just like Google Authenticator) seems to be way simpler. In any way, I'm curious ... How would it work if I (truly) decide to share my password with someone else I really trust. Considering that person have a different typing pattern than mine, even though I share my TypingDNA credential to him/her, he/she would not have access to the second-factor authentication codes ... right?
