Some ways to use PSPad without a PSN login
Some users have problems with the PSN login because either they don't want to perform a PSN login because of security concerns or because they receive some strange errors like "A connection to the server could not be established" from the official Sony login web-page. Please note: PSPad doesn't have at any time access to your PSN email address or password. PSPad is using the official PSN login web-page from Sony and PSPad only has access to your PSN Online-ID and your Account-ID after a successful login. These two data are stored encrypted on your device and nowhere else.
Why is the PSN login needed anyway? Well, since the PS4 firmware update 7.0 Sony decided to use the Account-ID for registering a Remote Play client with a PlayStation rather then using the Online-ID (PSN user name) like before. This Account-ID is a unique number which is an identifier for your PSN profile. Upon registering with your PlayStation this Account-ID must be sent to your console or it won't allow to register.
PSPad allows it to directly enter the Account-ID during the registration process by activating the "Advanced Settings", if you do so NO PSN login must be performed on PSPad. You can find below three methods of how you can query your Account-ID:
1. The most easiest way is to write me an email at f.grill160@gmail.com. All you need to tell me is your PSN Online-ID (your PSN user name/ nickname). However, as I really receive a lot of emails and handling all of them is sometimes not that easy you might want to try one of the two other options down below.
2. I have written a small program for Windows which allows it to query the Account-ID for a specific user which is available here. You must perform here a PSN login as well in order to query the Account-ID but the program is open-source and available here so you can verify easily by yourself that there isn't anything harmful happening. Some short instructions about the program can be found here.
3. You can go to a PC and open this web-page. Just follow all the instructions on that web-page. Please note, in the result of the trinket website your actual Account-ID is next to the user_id variable and should look something like this
'user_id': '4474834823397313449'
It consists ONLY of numbers. Thanks to CSystem77 for providing this script at trinket.io.
If you have successfully queried your Account-ID you can register with your PS5/ PS4 manually without performing a PSN login. In the Register view of PSPad just activate the "Advanced Settings" check "Register PS5 manually"/ "Register PS4 manually" and add the Account-ID in the textbox.
