jabber calendar - could not sign in - google calendar

[Mohammadreza Hadi]

hi dear friends,

when is choose jabber integration calendar with "google calendar",

jabber shows this error >> ( Couldn't sign you in, This browser or app may not be secure. Try using a different browser )

default browser engine is Chrome,

so i changed the jabber XML options, to use IE (internet explorer) engine,

but error still exist..

how we can fix that?

(see the attachment for error)

That appears to be a Google message/error, not Jabber itself. A quick search indicates you may need to enable “Allow less secure apps” in your Google account.

thanks dear @Jonathan Schulenberg 

you are right, this issue was because of "Google More Secure Apps" approach..

if we set an account without 2-factor authentication and also enable "less secure apps" setting in google, jabber will connect to google calendar.. 

but it seems google will not support "less secure setting" from 2023 and later
