Hi, is there any posibility to block email change in hosting authentication when i pass an email in login hint parameter?  
auth url looks like: “[Error During OAuth](https://api.eu.nylas.com/v3/connect/auth?client_id=clientid&redirect_uri=http%3a%2f%2flocalhost%3a4200%2fagency%2fconfig&response_type=code&login_hint=bartosz.g%40gmail.com)”

Hi @bartosz.grzeda what the error you is saying is that you don’t have a connector enabled. You need to go your Dashboard and enable it.

is it possible to force user to use only account with email i provided in auth url?  
i mean to block this “Użyj innego konta” option (use another account)

@bartosz.grzeda Sorry, not yet ☹ The Engineering team is on an off-site and slow to respond. I will let you know once they get back to me.

Alright, I got an answer, although probably not the one you expected ☹

**It is not possible unfortunately. But technically they can then remove the grant if the email didnt match what they wanted it to be.**  
**It would be the same even if they authenticated with google directly and then use custom auth**
