Create your account

Sign up with an email address. There is no password to choose or forget.

Lontly uses one-time codes instead of passwords. You enter your email, we send a 5-digit code, you type it in. That is the entire sign-up and the entire sign-in.

  1. 1

    Enter your name and email

    Use an address you can open right now — the code lands within a few seconds.

  2. 2

    Check your inbox

    The email comes from Lontly and contains a 5-digit code.

  3. 3

    Type the code

    You are signed in immediately and stay signed in on that device.

Signing in and signing up are the same screen — we recognise the address either way.

About the code

  • It is 5 digits and expires after 10 minutes.
  • Requesting a new code invalidates the previous one.
  • Codes are stored hashed, so nobody at Lontly can read yours.

Staying signed in

Your session lives in a secure, HTTP-only cookie that JavaScript cannot read. It refreshes quietly in the background, so you will not be logged out mid-edit. Signing out clears it everywhere on that device.
