Sign-in problems
Last updated 9 October 2026
Most sign-in problems are one of three things: the browser couldn't hand you back to ThatPrompt, the account has no password yet because it was created when you bought, or a link expired. Start a fresh sign-in from ThatPrompt each time, rather than reusing an old browser tab.
The browser doesn't come back to ThatPrompt
When you choose Sign in, ThatPrompt opens your browser and waits for it to hand you back, for up to five minutes. If it doesn't:
- Finish signing in within five minutes, in the browser window ThatPrompt opened.
- If ThatPrompt says Authentication timed out, choose Sign in again. An old tab won't work, because each sign-in is new.
- A VPN, proxy or browser extension that blocks connections to your own computer can stop the hand-back. Try with it off, or in another browser.
When it works, the browser tab says Signed in successfully and you can close it.
"Invalid email or password"
- Check the email is the one you bought with or signed up with.
- Bought on the website? Your account was created for you without a password. Use the link in your purchase email to set one. If you try to sign in first, the page emails you a fresh link.
- Otherwise, choose Forgot password? to get a reset link.
"An account with this email already exists"
You tried to create an account with an email that has one, often because buying created it. The page switches to sign in. Set your password with the link we emailed you, or use Forgot password?
"Invalid or expired link"
| Link | Lasts |
|---|---|
| Set your password, from your purchase email | 7 days, and works once |
| Reset your password | 24 hours |
Ask for a new one with Forgot password? on the sign-in page.
"Invalid login link. Please try again from the ThatPrompt app."
The sign-in page only works when ThatPrompt opens it. Bookmarks and typed addresses don't. Choose Sign in in ThatPrompt.
"Your session has expired. Please sign in again."
You were signed out, for example after a long time offline or after your devices were reset. Sign in again. Your licence and prompts are untouched.
"This account is already signed in on two devices"
See Use ThatPrompt on a second computer.
"Service is temporarily busy"
Too many attempts in a short time. Wait 15 minutes and try again.
