@roy0581 Are you getting the message "Enter your password to unlock keyring - The login keyring did not get unlocked when you logged into your computer", or an equivalent message?
If so, the problem might be that you are using Autologin.
I encountered a similar problem when I first started testing Edge-Linux on Solus Budgie, Ubuntu 20.04 and Zorin OS 16 Beta. As I explored the issue, I discovered that Chromium-based browsers (Chromium, Chrome, Vivaldi, Edge and so on) use the keyring to enable sync and password storage, and, as a result, require that the keyring either (1) be unlocked at boot, or (2) be unlocked each time a browser instance is opened.
If you are using Autologin, changing your settings from "Autologin - ON" to "Autologin - OFF" might resolve the issue. It did for me in all three cases. When the keyring was unlocked on boot, the keyring unlock was persistent, as it is supposed to be, and Edge-Linux no longer required unlock when opened or used.
I haven't used Mint for a number of years, but if I recall correctly, Mint uses the Gnome keyring, so the following might be of help: "The Keyring Concept in Ubuntu: What is It and How to Use it?" The article is about Ubuntu rather than Mint, but the interaction of the Gnome keyring and Chromium-based browsers are reasonably well explained.
