Sign in with a link by email
No password: the sign-in page emails you a link that works once. Open it in the browser that asked, and one press signs you in.
No password, or forgotten it? The sign-in page can email you a link instead. It signs you in, or makes your account if the address is new, and it confirms the address is yours, which starting a team, a team's join link or invitation, and a calendar that emails the people you book all ask for. "Continue with Google" and your password keep working beside it.
Ask for one
- On the sign-in page, type your address under "Email" and press "Email me a sign-in link", below "Continue with email". No password needed.
- "Check your email" says "If you can read email at …, a link is on its way. It works once, for 15 minutes." Every address gets the same words, so the page never tells anyone whether an account exists.
- Nothing after a few minutes? Look in spam or promotions, and check the address. "Email me another link" sends a new one.
A team's or a calendar's invitation has the same button, and its link brings you back to the invitation.
The email
"Your eKard sign-in link" doesn't assume you asked: "Someone asked to sign in to eKard as …. If it was you, this link signs you in: no password needed." For a new address, the link "makes your account and signs you in". Press "Sign in to eKard", or paste the address written under it. Signing in, with it or any other way, ends it and every older link. Didn't ask? Ignore it: nobody can sign in without the email.
Open it in the browser that asked
The link opens a page, "Sign in to eKard", with one button. Opening it signs nobody in, because mail scanners open every link in an email; the button does.
- In the browser you asked from, one press of "Sign in", and you stay signed in there.
- Anywhere else (another device, or a mail app's own browser), the page says "This link was asked for in another browser or on another device. It signs you in here until you close this browser."
An account nobody has confirmed yet becomes yours alone only from the browser that asked. The page warns first: "This will sign out every other device and browser, and remove the password and the AI key on this account." The button reads "Confirm and sign in". Opened anywhere else, the account stays as it was, unconfirmed.
A link for another account
Signed in as someone else in that browser? The page says "This link is for another account" and names both addresses. "Sign out and continue" signs you in as the link's address; "Stay signed in as …" changes nothing, and the link works until its 15 minutes are up.
When it doesn't work
"This sign-in link doesn't work any more" means it was used, ran out, or the account signed in another way since: "Ask for a new link". An address gets 5 links an hour from one network and 20 from anywhere, and the sign-in page says how long to wait.
The Android and iPhone apps don't offer the link yet. Sign in there with "Continue with Google" ("Continue with Apple" too on an iPhone) or "Continue with email" and your password. A link asked for on the web opens in your browser.
