# Add Social Media Accounts to a Warmr iPhone Device

> Log in to TikTok or Instagram on a connected iPhone, then add the account in Warmr so it begins warmup and joins the posting rotation.

Once your iPhones are connected, configured, and have the [runner installed](/setup/install-runner), you are ready to add social media accounts. Warmr supports TikTok, Instagram, X, and LinkedIn. You log in directly on the iPhone through the Warmr interface, and from that point Warmr takes ownership of the account, running warmup activity, tracking maturity, and slotting the account into the posting rotation when it is ready.

## Account limits by plan

| Plan  | Max Accounts |
| ----- | ------------ |

## Add an account

<Steps>
  <Step title="Select a connected iPhone">
    In the Warmr **Devices** panel, click the iPhone you want to add the account to. Confirm the device is online and the runner is installed.
  </Step>

  <Step title="Click Add Account and choose a platform">
    Click **Add Account**, then select **TikTok**, **Instagram**, **X**, or **LinkedIn** from the platform picker.
  </Step>

  <Step title="Warmr opens the platform app on the iPhone">
    Warmr launches the selected app on the iPhone automatically. You will see the app come to the foreground on the device.
  </Step>

  <Step title="Log in with your credentials on the iPhone">
    Enter the account's username and password on the iPhone. Complete any two-factor authentication or verification steps as prompted.
  </Step>

  <Step title="Warmr detects the login and registers the account">
    Once the login succeeds, Warmr detects the authenticated session and adds the account to the Devices panel under that iPhone.
  </Step>

  <Step title="The account enters warmup mode automatically">
    If the account is new or freshly created, Warmr places it into **warmup mode** immediately. It will not post until it has matured through the warmup phase.
  </Step>
</Steps>

## What happens after you add an account

<CardGroup cols={2}>
  <Card title="New accounts" icon="sprout">
    Enter the warmup phase automatically. Warmr runs daily scroll, like, follow, and search activity to build a genuine usage history. The account is locked out of the posting rotation until it matures.
  </Card>

  <Card title="Existing / aged accounts" icon="bolt">
    Already-aged accounts with an established history may pass through warmup faster and join the posting rotation sooner. Warmr evaluates each account individually.
  </Card>
</CardGroup>

<Tip>
  An iPhone can hold up to 8 accounts per platform, but **3–4 TikTok or Instagram accounts per iPhone is the best-practice sweet spot** for keeping them healthy. You can still mix platforms on one device, for example, a few TikTok accounts alongside a few Instagram accounts.
</Tip>

<Note>
  Warmr will not allow a brand-new account to post until it has matured through the warmup phase. This protects the account from early bans that commonly occur when fresh accounts post without any prior activity.
