I have installed deb file with this command sudo gdebi ./discord-0.0.47.deb
And also added Discord app to startup items, but everytime it opens (1st time during startup) it asks for authentications, same with other apps I installed via degbi. (pardon me Im new to linux, also I felt gdebi was easiest to install deb files.)
Please note: at login I have set to auto login me, and this spoils the startup speed.
Applications like Discord are built using a technology that embed the Chromium browser engine, which is what is asking to unlock the keyring. I assume the other programs you have trouble with are also built with this technology, or are Chromium-based browsers like Brave, Vivaldi, Google Chrome, etc.
