404: Page Not Found on "Visit our sign-up page..."

Hi folks,

A few notes here:

We're aware the page doesn't have any content (404) if you don't have the beta installed. That is expected at this point. As we move through the beta period we'll be looking to get some sort of placeholder up there, but the idea is that the link should be opening in 1Password, not your web browser.
tl;dr: What butterford said.

It may work best to try tapping the link from the Mail app on iOS, rather than an app such as Gmail which intercepts links you tap. This is an unconfirmed theory at this point. If you're having this difficulty and have installed the beta 1Password app from TestFlight, and you're using something other than Mail, I'd appreciate it if you could please try using Mail and see if that works better.

When I sign up, should I use my current account address or do i need to use a brand new email address?

A separate email address would be the best approach.

"When you’re asked to enter an email address, use an email address that isn’t tied to an existing 1Password account." from Unlock 1Password with a passkey (private beta)

Thanks for this batch of initial feedback, folks! If you've been having trouble please let me know if the above helps.

Ben
