I noticed this when I did a redemption earlier this week. I don't care about petty stuff like this. So long as the website works, I can accomplish what I need to do, and the process is well structured.
I quickly found where I needed to submit my redemption request, it was easy, I received immediate confirmation email, and 2 days later the funds were in my bank account. Success.
The One Time Passcode is (now) simply a form of 2FA. If they don't do it that way, then be prepared to hand over your cellphone number and receive SMS text on each login attempt. It's not a big deal, and it's there for the user's protection. The website has had real issues to complain about in the past. The One Time Passcode does not even register as an inconvenience in my view.
