If you have previously logged in to Flight Crew View using your Google or Apple account, but aren't sure how to log in on other devices, here are some steps you can follow:
Create a Password:
If you aren't logged in to your Google/Apple account on the other device, you will need to create a password and log in with email/password. You can easily add or update a password in the Settings page in the app.
Apple Anonymous Email:
If you are using an anonymous email provided by Apple's Hide My Email feature, you can find that email address in the Settings page, too. Just use that email and the password that you created to log in to your other device.
You can also change that anonymous email to your normal email there in the Settings page (requires verification).
If you have any trouble with it, or have any other questions, please send an email via the Contact Developer option in the app's menu or at email@example.com
