Enabling 2FA breaks sync

[khamidou]

A couple users have reported that enabling two-factor authentication for an already syncing account breaks the sync.

I run into this issue. To make it work again, i've needed to

• deactivate 2FA
• remove the application access in the security panel of my gmail account
• delete the account in Nylas
• re-add the account in Nylas

Confirmed

@tito @Cu8eR So, I tried reproducing the issue but couldn't. I followed the following steps:

1. Sync a Gmail account without 2FA with N1
2. Turn-on 2FA for this account
3. Observe that the account isn't syncing anymore
4. Delete the account from N1 and re-add it
5. Observe that the sync is working again.

Did you do anything else different? Did you try authenticating with an app-specific password?

Karim

@khamidou I have the same problem, on mac, do your steps, but not work for me, how to use app-specific password? N1 is using web login.

Sounds like it's happening Exchange as well.

Another report from Peter @ Nylas.

Same problem for me (on Mac). I used N1 for a while without problem but suddenly all my accounts that use 2FA don't sync anymore. Putting the password in again (for the gmail using web login) that I used in the first place doesn't help. I keep getting the message:

Several of you accounts are having issues. You will not be able to send or receive mail.

I contacted support and had them delete my old account data in an attempt to get around this issue, which did not work. Is there any eta for having this fixed? I have cancelled my Nylas Pro subscription in the meantime.

Having the same issue at the moment but I'm using a self hosted sync engine if that makes any difference.

It's called "Project Default Service Account" in my case which does not like a "proper" name. I would expect something like "Nylas something" related?
