<br>
In a Python plugin [1] we implemented HTTP "Basic Authentication" and<br>
"NTLM authentication".<br>
<br>
Now I'm still looking for a solution using OAuth 2.0 for build-in WxS<br>
(WMS/WMTS, WFS) as well as for Python plugins.<br>
This seems to be also of some interest for other QGIS users [2].<br>
<br>
<br>
The only code related to OAuth2 I found is in the CartoDB plugin [3].<br>
But this does not help WxS nor my Python plugin.<br>
<br>
Also Paolo's pointer to LizMap relates not to QGIS Python plugin but<br>
to restricted access to lizmap online AFAIK.<br>
<br>
I heard about the authentication configuration system with master password [4].<br>
But we still need more information when the API is available.<br>

</span>Any news on this, and on OAuth implementations for WxS and Python plugins?<br>
