Pokemon-go – I was updating the pokemon go and it said i had to delete it then log back in.

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.

I know you have already contacted them but your best action would be to wait to hear back from Niantic support and see if they are able to restore the account data to a new G-Mail or Pokemon Go account.

Your best bet would be to find any receipts of any in game purchases you made, through PayPal, bank card purchases etc as they will have a transaction ID that they may be able to link with your account.

Without this they have no way to confirm you are the original owner of the deleted G-Mail account and will probably not restore said account.
