The major site update in September enabled OAuth 2 authentication for OpenGeofiction, however we had to re-add support support for Basic Auth due to issues with JOSM. This work around has also reduced the speed of map uploads.
Good news: JOSM 19678 was released today. With it the fully automatic OAuth 2 authorisation flow works:

- Open JOSM preferences
- Select "OSM Server"
- Select
https://opengeofiction.net/apiin the "OSM Server URL" field and hit "Validate" - Hit "Authorise now (Fully automatic)"
- Your default web browser will be loaded with an authorisation page on OpenGeofiction, hit "Authorise"
- Return to JOSM, you can now upload to OpenGeofiction

The support for legacy Basic Auth will be turned off on Thu 3 Dec 2026, but it is worth enabling soon as possible to take advantage of the better upload experience.
