Signing in
Sign in opens a hosted sign-in page where you enter the email address you use with Manynote. Password resets and one-time codes happen on that page, not inside the app.
Manynote Reader is in early access. New accounts are created from the sign-up link on the home page.
If a sign-in link expired or the page shows an error, start again from Sign in. Links are single use, and a second attempt replaces the first.
If you cannot sign in at all, use the sign-in retry link on the error page; there is no separate email channel yet.
