OAuth2.0 authentication for Gmail

It appears Google has been recommending that applications move to OAuth 2.0 based authentication: http://googleonlinesecurity.blogspot.com/2014/04/new-security-measures-will-affect-older.html

I noticed that if emClient is only able to access Gmail if I enable access for “less secure apps”: https://www.google.com/settings/security/lesssecureapps

Are there any plans to switch to OAuth2.0 in emClient in line with this recommendation from Google? Alternately, is there any reason I should (or should not ) be concerned about this?

Hi, yes this is planned for future releases of eM Client, however it might be included in version 7 or some of it’s early updates.
We are not using OAuth at the moment since som of the features we were using were still not supporting this, however there’s no need to be concerned about eM client and OAuth at the moment since with eM Client your password and your data is still on your computer, you should only be concerned when using 3rd party apps, where you provide the password to a service that manages these data (online apps etc.).

Hope this helps,

Hi there, my university just switched to OAuth2 exclusively. Does eM Client support Exchange accounts with OAuth2? Thanks!

It does if you are accessing the account with IMAP. 

If you have a Pro License, you might want to open a support ticket with eM Client to get further details about EWS and 0Auth.

Will do, thanks! I’ll post back when I get a response from the ticket.

I received the following reply to my eM Client support ticket: “At this moment it is not supported and unfortunately due to some implementation difficulties I cannot provide any ETA but in general we would like to implement this functionality in the future.” Darn.


If your Exchange server also has IMAP, then you can use that for email as eM Client fully supports this type of authentication with IMAP accounts.
