## How does it work?
- [ViaVersion](https://viaversion.com), [ViaBackwards](https://viaversion.com/backwards) and [ViaRewind](https://viaversion.com/rewind) translates the connections to backend server.

- Due to technical/security reasons, 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 seems suspect.
- Account credentials aren't sent to VIAaaS instance, though it's intermediated by CORS Proxy.
- VIAaaS receives a session hash from instance and then authenticates the session hash with Mojang.
- VIAaaS receives a the session hash from instance and then the browser validates it to Mojang.

## Usage for players
Usage for offline mode:
- Connect to ```mc.example.com.viaaas.localhost```
- Connect to ```mc.example.net.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 and with no username verification. May be useful if you have a client which is incompatible with online mode).
(offline mode in frontend. May be useful if you have a client which is incompatible with online mode).
- Go to [VIAaaS auth webpage](https://localhost:25543/)
- Configure CORS proxy, see above in "CORS Proxy" section
- Listen to the username A you'll use to connect to the proxy.
- Keep the page open
- Add the account B to VIAaaS page which you'll use in ```_u(account B)``` parameter below.
- Connect to ```mc.example.com._u(account B).viaaas.localhost``` (```_u``` parameter can be removed if you are using the same username)
- Approve the login in auth webpage
- Keep the page open
- Connect to ```mc.example.com._u(account B).viaaas.localhost``` (```_u``` can be removed if you are using the same username)
- Approve the login in the webpage
- If you use the same online mode account, your client may show Bad Login. You can use a mod like
[Auth Me](https://www.curseforge.com/minecraft/mc-mods/auth-me) or [ReAuth](https://www.curseforge.com/minecraft/mc-mods/reauth) for reauthenticating the client.
[Auth Me](https://www.curseforge.com/minecraft/mc-mods/auth-me) or [ReAuth](https://www.curseforge.com/minecraft/mc-mods/reauth).
Example address: ```server.example.com._p25565._v1_12_2._of._uBACKUSERNAME.viaaas.example.com``` (similar to [Tor2web](https://www.tor2web.org/) proxies)
### Address options
Example address:
- ```server.example.net._p25565._v1_12_2._of._uBACKUSERNAME.viaaas.example.com```
- ```server.example.net.v_1_8.viaaas.example.com```
- It's inspired by [Tor2web](https://www.tor2web.org/) proxies.
Address parts:
- ```server.example.com```: backend server address
- ```server.example.net```: backend server address
- ```_p```: backend port
- ```_v```: backend version ([protocol id](https://wiki.vg/Protocol_version_numbers) or name with underline instead of dots). ```AUTO``` is default and ``-1`` is fallback if it fails.
- ```_o```: ```t``` to force online mode in frontend, ```f``` to disable online mode in frontend. If not set, it will be based on backend online mode.
- ```_u```: username to use in backend connection
- ```viaaas.example.com```: hostname suffix (defined in config)
- You can use ``(option)_(value)`` too, like ``.p_25565.``.
## WARNING
- VIAaaS may trigger anti-cheats, due to block, item, movement and other differences between versions. USE AT OWN RISK
- VIAaaS server instance may have security vulnerabilities, make sure to block the ports in firewall
- Take care of browser local storage. Check for XSS vulnerabilities on your domain.
- Check the security of CORS proxy, it will intermediate Mojang API calls.
- Mojang may lock your account when API is called from a suspect IP address
## FAQ
### Accounts
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

### Connection
How to use IPv6?:
- When listening to 0.0.0.0, it should listen on IPv6 too.
- To use IPv6 in backend address, you need to use a instance with IPv6 connectivity. The hostname parser currently doesn't support

```
- If you are using a public GeyserConnect instance: connect to a publicly available VIAaaS instance, like ```mc.example.com.viaaas.example.net``` as a Java Edition server.
How to connect to 1.7.10 and lower servers with a newer client?
- Use [DirtMultiVersion](https://github.com/DirtPowered/DirtMultiversion)
Can I use it to connect to .onion Minecraft hidden servers?
- You can use .onion addresses if the instance is proxying the backend connections to TOR.
Note that VIAaaS may log your requests.
Can you support more versions?
