First I had to log into ebay - no problem, got my password manager right here, as soon as I unlock my phone with my fingerprint. Now I'll just key in my 12 character, randomly generated password with mixed case letters, numbers and symbols.
Then ebay decided they wanted to send me a code by SMS. I'd never enabled that security option, but whatever. I can do that, quick fingerprint to unlock the phone then key in the code.
Then I chose to pay with paypal, requiring a second password. And a 2FA code, this time from a TOTP app. For some reason paypal ask for TOTP every time. Easy enough, quick fingerprint auth then just key in the code.
Then I told paypal I wanted to pay by card, as I always do. They redirected me to my bank, who asked me to use their mobile app to authorise the payment with my fingerprint. After unlocking my phone with my fingerprint, naturally.
Clearly, the days when businesses thought online shopping ought to be low-friction are long gone.
