@BeAware In practice it should work this way: you enter either the address of your PDS, or your handle which is resolved to your DID which is then used to find the address of your PDS, then the app contacts your PDS to authenticate to your account and get back access token from the PDS. If your on your own PDS then none of your account data is hosted on Bluesky servers except the (public) DID JSON file on plc.directory.
