Login with Lightning
No passwords. No email. Just scan a QR code with your Bitcoin wallet.
What is LNURL-auth?
LNURL-auth is a simple, secure way to log in to websites using your Lightning wallet. Instead of creating yet another account with a password you'll forget, you just scan a QR code.
Your wallet signs a cryptographic challenge that proves you own your keys. No personal information is shared. No password can be stolen. It's the Bitcoin way.

Frequently Asked Questions
Is this safe?
Very safe. LNURL-auth uses public key cryptography - the same technology that secures Bitcoin itself. Your wallet signs a unique challenge for each login. Your private keys never leave your device.
What if I lose my phone?
Your account is tied to your wallet's keys. If you have your wallet backup (seed phrase), you can restore it on a new phone and log in again. This is why backing up your wallet is important!
Can I use multiple wallets?
Each wallet has a unique identity. If you log in with a different wallet, you'll have a different account. Stick with one wallet for consistency.
Does this cost anything?
No! LNURL-auth is completely free. It doesn't send any Bitcoin - it just proves you own your wallet. There are no fees involved.
What data do you collect?
Only your wallet's public key (a random-looking string). We don't know your name, email, location, or anything else. That's the beauty of Bitcoin-native authentication.
