If your organization invited you, start from the link in the invitation email. Use the email address that received it. AIRCTRL adds you to the organization after you finish the required setup. > [!NOTE] > > Already have an AIRCTRL account with that email address? Sign in to it instead of creating another one. Complete the two-step verification method already set up for that account. New accounts complete the setup below. On an existing account, AIRCTRL skips any setup steps you have already completed. ## 1. Open the invitation link If this is your first AIRCTRL account, the link may ask you to set a sign-in password. Create it and continue. If you already have an account, sign in with your existing password instead. ![Invitation page asking a new member to set a sign-in password.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/01-set-password.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=e755762e921e7153e47dca42b55bfb9a) Set a sign-in password if the invitation asks you to finish joining. ## 2. Set up two-step verification New accounts must set up two-step verification before entering. If AIRCTRL asks you to enroll it, choose **Authenticator app**. If two-step verification is already enabled on your account, complete the check shown after you sign in instead of enrolling it again. ![Two-step verification setup with the authenticator app option.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/02-two-step-verification.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=e0e1469809bcc75b3f947dd1bc0d7295) Choose the authenticator app for two-step verification. ## 3. Connect your authenticator app When you enroll a new authenticator, scan the QR code with the app. If you cannot scan it, enter the setup key shown on the screen. Then enter the six-digit code from your authenticator app to verify the setup. Keep the QR code and setup key private. Do not send them to the person who invited you or to support. ![Authenticator setup screen with the QR code and setup key hidden.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/03-authenticator-setup.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=b301eaf4f042547eed1dfea8074fe0b5) The QR code and setup key are hidden in this guide image. Keep the values shown in your account private. ## 4. Save your sign-in recovery codes When you set up two-step verification for the first time, save the recovery codes before you continue. Each code works once if you cannot use your authenticator, and AIRCTRL will not show this set again. These codes are for signing in. They are different from the vault recovery kit in step 7. If you leave before saving them, they stop working. Generate and save a fresh set when you return. ![Two-step verification recovery-code screen with all code values hidden.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/04-save-sign-in-recovery-codes.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=64e2eb06adfbcb9e9c4f55067a89399b) Save the one-time two-step verification recovery codes before continuing. Their values are hidden here. ## 5. Complete your profile Enter a display name and a unique username. Both are required. Your display name is how teammates see you; your username is your account handle. Follow the rules shown under the username field. ![Profile setup with required display name and username fields.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/05-profile.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=70520f1b755e8b6cee1488224b37ea8f) Enter the display name and username you want teammates to see. ## 6. Set your vault passphrase Create and confirm a vault passphrase with at least 10 characters. It is different from your sign-in password. AIRCTRL does not see this passphrase and cannot reset it, so keep it somewhere safe. ![Vault setup explaining the separate passphrase and showing the passphrase and confirmation fields.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/06-vault-passphrase.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=e55a9e32eac401043a08675c521f419f) Create and confirm the passphrase that protects your vault on this device. ## 7. Save your vault recovery kit Save the recovery code or recovery phrase, or download the recovery kit. You need one of these if you forget your vault passphrase. They do not sign you in to your account; you still need your account sign-in. The vault recovery kit is different from the two-step verification recovery codes in step 4. Keep both types private. If you leave before saving the kit, AIRCTRL asks for your vault passphrase so you can generate a fresh kit when you return. ![Vault recovery screen with the recovery code and recovery phrase hidden.](https://mintcdn.com/airctrl/XQVytqi_NP8l26YA/images/app-guide/invitations/07-vault-recovery-kit.png?fit=max\&auto=format\&n=XQVytqi_NP8l26YA\&q=85\&s=ba2ece2ce6509c45178f0bfaa09a7ef4) Save the vault recovery code or phrase, or download the kit. The values are hidden in this guide image. ## After setup When the required setup is complete, AIRCTRL accepts the pending invitation and opens the organization you were invited to. Your access follows the role chosen by the person who invited you. You do not create a second organization as part of joining. If you choose **Finish later** during setup, AIRCTRL signs you out. Sign in again with the invited email address to continue. You cannot open the organization until the required setup is complete. If the invitation link cannot be accepted, check that you are using the invited email address and ask the person who invited you to review the invitation. They can find pending invitations in [Manage access](https://docs.airctrl.dev/app-guide/access.md).
