GXB LLC runs GXB Auth, the sign-in service at auth.gxb.vc. Some accounts can get a copy of their sign-in code by text message. The texts are optional, and the service works by email without them.
The code, and our name.
We charge nothing for the texts. Message and data rates may apply. Check your phone plan for details.
The texts come from Twilio's service numbers on behalf of GXB Auth. The number can change from one text to the next. Replies to these numbers, including STOP and HELP, are not read by us and may not reach anyone.
To stop the texts, remove your phone number on your profile page. You confirm the removal by email. You do not need the old phone to remove it.
If we recorded a carrier block, adding the number again does not turn the texts back on. A START reply also does not restore consent in the app. Email us (see Support below) about a block.
For help with sign-in texts, email christian@gxb.vc with the subject “GXB Auth SMS help”.
You can also remove your phone number yourself on your profile page at any time.
