# Accounts and sign-in

Altitude currently presents three sign-in paths.

## Wallet

Select **Connect Wallet** and choose a supported wallet from the connection modal. The wallet may be used to prove ownership and authorize supported actions. Read the wallet prompt before signing.

## Telegram

Select **Continue with Telegram** to authenticate through Telegram. Confirm that any authorization page belongs to Telegram and returns to `trade.reachaltitude.xyz`.

## Passkey

Select **Continue with Passkey**, then choose:

* **Sign Up with Passkey** for a new account.
* **Login with Passkey** for an existing account.

Passkeys use the authentication mechanism provided by your device or password manager. Add a second recovery method when possible before removing an existing passkey.

## Beta access code

New accounts may see **Access code — Enter an access code to join Altitude**. The current beta code is `ALTITUDIO`.

## Username

A username helps distinguish your public profile. If the claim step is optional, you can continue and set one later from **Profile**.

## Log out

Use the **Log Out** icon in the side navigation. Logging out ends the Altitude session; it does not disconnect or delete an external wallet.
