If Facebook login was your method for login you will now need to create a password.
Transitioning from Facebook login to Email login will retain all of your data, such as missions, distances etc.
A few important things to be aware of are:
The email address that was linked to your Facebook account when you signed up to My Virtual Mission is the email that we have associated to your My Virtual Mission account. This may be different to the email you currently login to Facebook with.
This email address is the one that the password creation link will be sent to.
If you no longer have access to that email you will be able to log in on a computer via the website (https://www.myvirtualmission.com/) and change you email in the "My Account" / "My Settings" page.
