Expand iPhone Face ID for login with app.
I am upvoting this because it seems fine with me. I suppose adding biometric authentication to the mobile app would include finger print for iPads and older iPhones. I suppose Android has a version too.
I haven't supported adding more security to web app as I like staying signed in, and any time I sign out, I get a text message code. But it is ok with me to add biometric authentication to that as well (since Macs support this) and adding passkeys.
