Account and Access Problems

Sign-in failures, missing roles, forgotten passwords, and invitations that do not seem to work.

Sign-in here has two steps, so knowing both helps with failures:

Password proves you are the account owner.
A one-time login link, sent to the account's email, is the second, out-of-band proof. The link is single-use and expires after a short time.

That second step is your multi-factor: something you know (the password) plus something you have (the inbox).

Invalid email or password.

The most common cause is a typo. Re-check both fields. The email is the account identifier, and the password is case-sensitive.
If you are a newly invited user who has not finished sign-up yet, you do not have a password to try. Use the sign-up link from the invitation email; that is where you set your password.
If your account's role changed, sign-in still works. Only what you can see after changes.

Wait up to a minute; check the spam and promotions folders.
If it is really not there, start sign-in again; each attempt issues a fresh link. Old links are single-use and expire, so this is harmless.
If emails to this address are not arriving at all (a broken mail server), contact your account administrator. See Getting help.

Each login link is single-use. If you opened it in two tabs, the second one fails. Start sign-in again.
Links expire after a short time. Start sign-in again.

Check Organizer → My Events; your event should be listed there.
If it is not, the assignment is missing. Your account administrator can assign you to the event (see Getting help).
If you are on a guest machine, sign in fresh in that browser.

Problem	Fix
Invitee got the email but the link does not work	The link expired or was revoked. Send a fresh invitation.
Invitee already has an account	The invitation assigns the event/role to the existing account. No new password needed.
I invited the wrong email	Have the invitation withdrawn and a new one sent to the right address. Your account administrator can do both.

Forgot password? Enter the account email and a reset link is sent to it. Open the link, set a new password, and sign in with it.
Reset links are single-use and time-limited, like login links.
The new password applies immediately; older sign-in sessions keep working until they are used.

Roles are set for the account by your account administrator. On your event, you can invite a new person as a tabulator yourself (see Your event). Any other role change, or access to a different event, goes through your account administrator.
A role change takes effect the next time the person loads a page. Signing out and back in makes it immediate.
