Sign in with X

Prove which X account is yours, then link it to your Mitoshi account with one signature — so a call you post trades for that account and no other.

Sign in with X

On Trade from X, Sign in with X sends you to X to approve tweet.read and users.read — nothing that posts. Mitoshi reads your profile once and drops X's token. The sign-in is single-use and bound to the browser that started it.

In the phone app, the X sign-in opens in the system browser and one tap brings you back to the app.

Link @you asks your passkey or wallet to sign a short text naming the network, your X account and your Mitoshi account, ending "Mentions of the Mitoshi bot may trade from my X trading balance only." From then on a call that X account posts trades for that Mitoshi account only.

  • One X account routes to one Mitoshi account. If it already routes elsewhere, the page offers to sign in as that account instead.
  • Unlink X is another signature. Your money stays where it is.
  • Account & keys shows the linked X account under Security.

On 13 October a passkey-shaped account's signature over that text verified, and the same signature for another X account did not (evidence).
