Click on the profile avatar or username to edit.
Personalize your account by changing the profile picture and username. The user can upload a profile picture or take the picture with the camera in his device. The image can be cropped before saving.
Once you have edited the profile image and/or nickname, be sure subsequently create a new backup to preserve the edits.
You can now log in and out at will on the current device by entering your password only; unless you delete the user, use a new browser, or clear the browser cache. In which case, you can use your backup file to restore your profile.
