I'm in the process of introducing authentication into The Next Guess website. At the moment, it is optional. There is a sign-in option in upper right. But at some point soon it will be required. I'm doing this for 2 primary reasons:

1. The user customizations right now are all stored in local browser storage (examples are storing Team Favorites and the Play By Play column and filter settings). If you clear your browser cache or use multiple browsers or computers, those customizations are not preserved and don't transfer. With authentication and a user profile, those customizations can be stored in a database with your user profile. So whenever/wherever you login, those customizations will be applied automatically.
2. I want to block bots from scanning and causing unnecessary/unwanted traffic to my site.

I'm using passwordless auth, so I won't be storing any passwords. You register your email and it sends you an OTP (one-time passcode). As long as you visit roughly once per month (from the same browser) you should never have to enter another OTP. If you login from a different browser, you will need to the enter the OTP you received via email.

Finally, don't worry, the site is still free to use, although donations are of course greatly appreciated.

Heads up - you will start seeing a modal dialog suggesting you create account/sign-in. An account remains optional for the next 2 weeks. Starting Sept 5th, I plan to require an account to use the site.

For those of you who have tried creating an account and authenticating to Next Guess, any troubles? Did you receive the email OTP code ok or did it happen to go to spam folder? Any other notable issues or concerns to report?

Nothing happened the first time I tried. The second time worked just fine. Sorry, I don't remember the dates

I received the email and code. Entered the code a few times. It continually asks me to authenticate and sign in. Appears it doesn't remember my PC and that I've already signed in.
