Solution 1:
Update to the latest version of Syntorial via your online account. If that doesn't work…
Solution 2 (if you purchased Syntorial before July 28, 2025):
- Log into your online account
- In the Syntorial section, click "Authorizations"
- De-Authorize all CPUs and iPads
- Try authorizing Syntorial again
Solution 3 - Syntorial V2 - Browser Login doesn't redirect back to Syntorial
- After you complete the browser log-in, you should be redirected back to Syntorial. If not…
- You'll see a temporary login token. Copy it.
- Go back to Syntorial, paste the token in, and submit.
Solution 4 - Syntorial V1 - iPad
Here are some issues that can sometimes arise when:
- Copying/pasting your info. Try instead manually typing in your email and password.
- Using a password helper app. Again try entering your password in manually.
- Using a connected keyboard. Try instead using the iPad onscreen keyboard.
- Using the TAB key to switch from the email field to the password field. Try tapping into the password field instead.
- Does your password have spaces in it? Reset your password to one without spaces.
- Make sure your email address is all lowercase.
