Some users are asking "why can't I log into Rizful.com with Nostr"?
We really considered this while building the service... the problem is that there have been many high-profile hacks recent of similar services, which were found to be mixing up user's Nostr keys with access to their funds.
Here is our FAQ on this issue:
Can I log in with my Nostr account?
We have carefully designed Rizful for maximum security. At the same time, we have found that too many Nostr users have poor security practices with their private keys. (For example, entering private keys into many websites and apps.) Since real money is involved, we don't allow users to login via Nostr, and we don't ever ask for your private Nostr key. A combination of email/password, plus optional two-factor authentication, is the battle-tested and secure way to protect your Rizful account. This also means that, if, in the future, you make a mistake with your Nostr keys, your Rizful account won't be vulnerable.
