Unable to login after upgrade to 1Password 8

Hello @JeroenG,

Thanks for your message and the latest update about the security policy blocking the 1Password traffic. Please let us know if you have further questions.

@Kletus, since you've mentioned you can sign in through your mobile device, I'd expect you can also sign in from 1Password.com (or .ca/.eu). If you can confirm this to be the case, can you try the following?
1. Sign in to 1Password.com (or .ca/.eu).
2. Select your name from the top of the right sidebar > "Get the apps".
3. Under Step two, click the "Add your account directly" button.
4. Select "Open 1Password for Windows desktop".
5. Sign in with your account password.

If your still having troubles, can you send a 1Password diagnostics via email to support+windows@1Password.com so we can help to investigate further? Please do not post these details in the forums.

Could also include a link to this thread in your email, along with your forum handle so we know it's you when your message arrives. Thanks!
