Cannot Sign In

What to try when sign-in will not complete, and why you can keep working in the meantime.

Before anything else, the good news: you do not need to sign in to use livediagram. The canvas always works without an account, so a sign-in problem never blocks you from building or sharing a document. You can continue as a guest and sort the account out later. With that safety net in mind, here is how to get sign-in working.

First, keep working

If sign-in is failing and you just want to get on with it, leave the sign-in page and head straight to a new document or the Explorer. Everything works: persistence, sharing by link, and real-time collaboration (only publishing to the Community needs an account). When you sign up or sign in later, the documents you built as a guest move into your account automatically, so nothing is lost, and you're offered the chance to move any documents in This Browser. See working as a guest.

Sign-in checklist

A wrong code shows an error above the form. Choose Send a new code for a fresh one, or Use a different email to change the address.
  1. Check the email code. Sign-in uses a 6-digit code sent to your email, valid for 5 minutes. Look in spam. If it is slow or has expired, choose Send a new code (it is available 30 seconds after the last one) and use the newest code: an earlier one stops working. Typing or pasting all six digits signs you in on its own. Three wrong tries use a code up; send a new one.
  2. Use the same email you originally signed up with. An address that has no account yet is not turned away: the code creates a new, empty account for it. Choose Use a different email on the code step if you mistyped it.
  3. Reload and retry. A stalled sign-in form usually clears with a refresh.
  4. Disable interfering extensions. Privacy or script-blocking extensions can break the sign-in flow. Try an incognito window with extensions off.
  5. Check the Google option. If you signed up with Google, use Continue with Google rather than the email code. It takes you to Google and back in the same tab, so allow the redirect and third-party sign-in for the site if your browser blocks them.

If sign-in is not available at all

On some deployments, sign-in is simply not turned on. This is a fully supported mode, not an error.

  • If the sign-in page says "Sign-in isn't turned on for this site", the instance is running in guest-only mode. There is no account to sign into: choose Continue as guest.
  • This is common on self-hosted instances. See configuration and optional auth.

If you are on the hosted site, expected sign-in to work, and it still will not complete after the checklist above, contact us with the email address you are using and the error you see. Keep working as a guest in the meantime, your documents are safe.
