Yesterday i started playing osm and i signed a contract with the manager name ‘toprednax’. I have never had to give my email or password. This morning when i started the app on my phone is was logged out. Now i can’t log back in because that account is not linked with an email or password. Is there any way i can get my account back? Please.
First read the OSM Terms On point 2 you'll see that you can't create/have more than one OSM account.
Now and for next time contact support by email; En.email@example.com explaining clearly the issue and include your manager names in the mail as well.
