IAS 9.0.0-beta.4 (for Quilt 1.18.2)

DISCLAIMER

This is a testing build of new IAS v9. It has some bugs (probably) and if you will rollback to v8, you will have to readd your accounts.

What's new in 9.0.0

Rewritten all code from the ground up using modern Java (17) and modern Minecraft API. (Probably fixed some bugs and added some more due to this)
Refactored the project to allow easier cross-loader and cross-version development.
Added access/refresh token encryption with hardware or password key at your choice. (To combat token stealing and accidental token sharing; It's possible to opt-out of token encryption but it's UNSAFE and is disabled in the config by default)
Added a lot of things to prevent token stealing and accidental token sharing. (Encryption mentioned above; Moved accounts out of config folder; Added disclaimers and "loud" file names into the new folder; Added info on how to "revoke" all tokens)
Added Forge, NeoForge, and native Quilt support.
Some authentication errors will now use more detailed/helpful messages.
Authentication link will be now copied to clipboard.
Improved security and fixed some bugs for Microsoft authentication. (Also added alternative authentication method similar to MultiMC/Prism)
Used new skin widgets (used for skin reporting by Mojang) to preview skins.
Added an option to show nick in the server list. (Enabled by default; Can be disabled)
Enabled button in the server list by default. (Can be disabled)
Auto-moving IAS button to the right if there's another mod button in the way.
Added a lot of various tooltips.
Prevent invalid offline names (too long, too short, containing invalid characters) by default. (Can be overridden)
Added toast notification (warning) for invalid offline names when joining a server. (Can be disabled)
Added an option to show current username in the game title bar. (Disabled by default)
UI was rewritten. (Main UI is mainly untouched; Account adding/removing/editing/using screens remade into "fluent popups"; Config UI is changed slightly; Keybinds will work in some GUIs; Double clicking an account will use it; Accounts will show tooltips)
Added a few unexpected pigs. (easter eggs)
Added some help pages.

What's new in 9.0.0-beta.4 (in comparison to 9.0.0-beta.1)

Updated to support 1.20.6.
Ported to 1.20.1, 1.19.4, 1.18.2.
You can now completely disable password echoing, not just replace it with stars. (Like in UN*X shells)
New tip about not using MS account password as Crypt password.
Fixed config path on Forge and NeoForge.
Accounts with same name but different UUID will be highlighted with yellow color in the menu.
Accounts with same name but different name case will be highlighted with orange color in the menu.
Fixed "warning" icon height.
Renamed "/auth.html" to "/ias_auth.html" to prevent any mod conflicts.
Remade "You can close this window now" page.
Fixed a bug where account moving was possible when account was not selected yet.

Known issues

Skin widgets won't render on 1.19.4 and 1.18.2. (They work just fine with 1.20.1, 1.20.3, 1.20.4, 1.20.6)
UI, especially tooltips, is very broken with 1.18.2. (Newer versions work just fine)

Where's beta.2 and beta.3? Nowhere.
