The menu login in war thunder using psn / xbox / etc not available
Currently it’s not possible to transfer your account, but you should be able to get all your standard tech tree progress (but not premiums or golden eagles) you might need to link your account to your email address somehow.
how to link the account
Try using web login.
Note that some have had issues using firefox with the above method.
Here is information about that part:
Transfer shouldn’t be necessary to just play on PC. It’s just that some options won’t be available but you can still play on PC.
True, I tested it a few years ago and it worked (had all my tech tree progress) but I immediately uninstalled because no GPU lol.
