## In short

A [bio code](https://satt.com/guides/glossary#bio-code) proves you control a social account without the official connection: SaTT gives you a one-time code such as `SATT-7K2Q9`, you paste it into your public bio within 15 minutes, and SaTT re-reads the profile. It works on YouTube, X, TikTok and Instagram; it does not work on LinkedIn.

## What is a bio code?

A bio code is a short, single-use proof of control. Only the owner of an account can edit its public bio, so a code that appears there proves ownership.

An account verified this way is a [verified account](https://satt.com/guides/glossary#verified-account) shown as “verified by bio code”. Its posts can be paid like any other verified account.

## How does bio code verification work?

1. Choose the network and type your handle, then ask for a code.
2. SaTT returns a code like `SATT-7K2Q9`. It is valid for **15 minutes** and bound to your SaTT account or wallet.
3. Paste the code anywhere in the public bio (or channel description on YouTube) and save.
4. Press **Check**. SaTT reads the public profile; if the code is there, the handle is linked as verified.
5. You may remove the code from your bio afterwards.

Each code allows at most **10 checks**. If it expires, request a new one. Only owner-controlled fields count (bio, description, name); comments or recent posts are ignored.

## Which networks support it?

| Network | Bio code |
| --- | --- |
| YouTube | Supported (channel description) |
| X | Supported |
| TikTok | Supported |
| Instagram | Supported (public biography) |
| Facebook | Only when a profile provider is configured |
| LinkedIn | Not supported: no readable public bio |

The app shows the “Can’t connect? Verify with a bio code” link only on networks where the code can actually be checked right now. A private profile cannot be read, so make it public during the check.

## When should you use a bio code instead of OAuth?

Prefer the [official connection](https://satt.com/guides/glossary#oauth): it also lets you pick your own posts when you apply and see official statistics. Use a bio code when the official connection is not available to you, for example Instagram or TikTok during the alpha, where the official apps accept only test accounts.

To earn the [Verified creator](https://satt.com/guides/features/verified-creator-badge) badge you still need at least one network verified by its official connection. Step by step: [Verify with a bio code](https://satt.com/guides/how-to/verify-with-bio-code).

## Key takeaways

- A bio code is a one-time code valid for 15 minutes, with up to 10 checks.

- Supported on YouTube, X, TikTok and Instagram; not on LinkedIn.
- A bio-code account is verified and can be paid.
- The Verified creator badge still needs one official connection.

## Frequently asked questions

### Why does the check say the code was not found?

The profile may be private, the bio not saved yet, or the network slow to show the change. Wait a minute and check again; each code allows 10 checks.

### Do I have to keep the code in my bio?

No. Once the account is verified you can remove the code. The verification stays on your SaTT account.

### Can someone else verify my account with a code?

Only someone who can edit your public bio. The code is bound to the SaTT account that requested it and expires after 15 minutes.
