Have a way to save credentials when authentication fail

[Mereck13579]

Basically I sometimes get some "authentication failed" error that I don't know the cause of (re-authenticating works just fine).
The issue is more of QOL as I have to re-enter every single field each time (Client ID, client Secret, Username, Password). Could there be a way to save them when authentication failed for retry?

It is difficult to guess what's happening here. Any chance you can open the console and see if there are any helpful logs when you get the authentication failed?

Sure, I'll try to get you that next time it happens (unfortunately it's pretty random so I have no idea when I'll get that info)

Just happened now. Here is the console output (I guess the first time was automatic at launch or something, I only noticed by pressing the sync button manually, getting an error, checked the console at that moment):
Likely the token expired, refreshing it.

Small edit:
After that, if I click sync again it just says "Please authenticate with Wallabag first.", no additional log in console (and same problem happens, ID Secret etc is empty again)
