Pokemon-go – Can’t log into PokeGo. Not accepting any of the possible email accounts!

When you create an account you either have to have a password for your pokemon trainer account, or log in through your google account, which would mean your google username and password. This means you can't start without having a password.

If these options aren't enough, you can probably find a relevant topic or email address to contact Pokemon Go support on their website. https://support.pokemongo.nianticlabs.com/hc/en-us

*on a side note. As long as you can provide Niantic with the info registered to the account they should be able to recover it (i.e. email adress, original user name, etc). But yeah, if you are registered with Google it shouldn't be having problems.

There are a number of possible solutions:

1. Settings --> Privacy and safety --> Location: Check if "Location" is On. Then click on Location method and enable the method including GPS, Wifi and mobile networks
2. Switch Airplane mode On, wait half a minute or so, then turn in Off again
3. Make sure that Wifi is turned on, even if you are in a non-Wifi area (see 1.)
4. Go outdoors into an area where you can see a big part of the sky
5. Restart the app (make sure you properly close it)
6. Restart your phone and check with another app if your location is found before you start Pokemon Go
7. Check if you have the latest version of Pokemon Go installed
8. I think in newer Android versions than mine, you can specifically set permissions for each app individually. If that is the case, check if Pokemon Go is allowed to use the GPS
9. I am sure there is something more... I'll update this list if somebody comes up with another idea
