Steps
- Open the app. When you are logged out, the Log In screen is the first screen.
- Enter your Email and Password. Your phone's password manager can fill them in.
- Tap Log In. The button reads "Logging in..." while LotJitsu checks your details.

The app opens on Catalogs. It stays logged in, so next time it opens straight to your catalogs, even with no connection.
If it doesn't work
- "Incorrect email or password." Check for typos and capital letters, then try again. Forgotten it? Tap Reset Password at the foot of the screen. See Reset your password in the app.
- A "Verify your email" panel means you haven't opened the verification link yet. Tap Resend Verification Email, then open the newest email on this phone. See Verify your email address.
- "Your account has been locked due to too many failed login attempts. Please try again later." Wait a while, or reset your password.
- "An unexpected error occurred. Please try again later." The app couldn't reach LotJitsu. Logging in needs a connection. Check it and try again.
More fixes: Trouble logging in.
Sign out
