* If you believe this is an error, please feel free to contact our support team at <support@backpack.exchange>.

<summary>How can I ensure the security of my account after registration?</summary>

<summary>D<strong>o I need to complete KYC again if I change my personal information?</strong></summary>

* Yes. If your legal name, address, or identification documents change, you may be required to update your KYC information and undergo re-verification.
* Please use the email address registered with the exchange to send a change request to <support@backpack.exchange>, and we will process it as soon as possible.

<summary><strong>Can I change my KYC information to another person (i.e., transfer my account)?</strong></summary>

No. Exchange accounts are personal and non-transferable. KYC ties the account to the verified individual (or entity for corporate accounts). You may update your own details (e.g., new passport, legal name change, address) with supporting documents, but you cannot replace the verified person.

* If another person wants to use Backpack, they must create their own account and complete KYC.
* Sharing or selling accounts is not allowed and violates our Terms.
* For business use, apply for an entity account instead.
* Need to correct your information? Contact <support@backpack.exchange>.
