Am using a Free for Teacher account. Have a student who is successfully registered for the course. However, appears to be a password problem. (The username is correct.) When he tries to access the course either from the internet through canvas.instructure.com or through the app, he can't get in. When he tries to re-set password, Canvas redirects him to the original login screen. Plus now he's been locked out due to too many failed login attempts. Solution???
