-
VIAaaS auth page is designed for storing accounts in the player's browser local storage. It requires a CORS Proxy for calling Mojang APIs, which may make Mojang see that as suspicious and reset/block your account password if the IP address is suspect.
-
There are some information about Mojang password resetting: https://github.com/GeyserMC/Geyser/wiki/Common-Issues#mojang-resetting-account-credentials and https://mobile.twitter.com/MojangSupport/status/863697596350517248
-
VIAaaS may have security vulnerabilities, make sure to block the ports in firewall and take care of browser local storage.

Requires Java 11
How to start VIAaaS server:
java -jar VIAaaS-all.jar
Usage for offline mode:
- Connect to
mc.example.com.viaaas.localhost
Usage for online mode:
- You can use two accounts (avoids Bad Login error), the same account for front-end and back-end connections or use
_of(offline mode in frontend, unencrypted). - You should set up a CORS Proxy (something like https://www.npmjs.com/package/cors-anywhere,
git clone https://github.com/Rob--W/cors-anywhere && cd cors-anywhere && npm install && node server.js) on the machine you are using the VIAaaS authenticator webpage. You can use my CORS Anywhere instancehttps://crp123-cors.herokuapp.com/when using this page https://viaversion.github.io/VIAaaS/ but Mojang may see it as suspect. - Go to VIAaaS auth webpage (https://localhost:25543/), configure the CORS Proxy URL (something like http://localhost:8080/, note the ending slash) and listen to the username A that you're using to connect to the proxy.
- Add the account B you'll use in
_u(account B)parameter to browser auth page. - Connect to
mc.example.com._u(account B).viaaas.localhost(_uparameter can be removed if you are using the same username) - Approve the login in auth webpage
- If you use the same online mode account, your client will give Bad Login after you approve it in your browser. You can use https://www.curseforge.com/minecraft/mc-mods/auth-me for reauthenticating the client.
WARNING
VIAaaS may trigger anti-cheats, due to block, item, movement and other differences between versions. USE AT OWN RISK
FAQ
VIAaaS is stuck when connecting with online mode:
- Your system may have low entropy, see https://wiki.archlinux.org/index.php/Rng-tools
My Microsoft account <18 years old is not able to log in, it's giving XSTS error:
- Add your account to a family (see https://wiki.vg/Microsoft_Authentication_Scheme#Authenticate_with_XSTS)
Why a online webpage for online mode?:
- It's easier to maintain in that way, because providing a chat with login requires encoding and decoding more packets which change through versions.
- It allows your account password and token to be kept with you
