Another alternative is to use the API, set a password using authmod https://server.screepspl.us/web
has a change password page, as does any other server running screepsmod-auth and screepsmod-admin-utils.
Then a simple script like this should set the badge (place in empty folder, npm install screeps-api
, then run)
const { ScreepsAPI } = require('screeps-api')
ScreepsAPI.fromConfig('splus1').then(async api => {
const ret = await api.raw.user.badge({ type: 24, color1: '#ff0000', color2: '#ffb400', color3: '#ff6a27', param: 0, flip: false })
if (ret.ok) console.log('Badge Set')
})
