 ## How do I create a backup of my Universal Profile?
 
 If you lost access to the Universal Profile Browser Extension, there are multiple ways to secure your Universal Profile :
 
-- **2FA**: You can set up 2FA while creating the profile on [UniversalProfile.cloud](https://universalprofile.cloud/). 2FA is the recommended way of backing up a Universal Profile and will add a new recovery controller to the profile, secured on LUKSO's end. This controller has permission to add new controller keys if access to an old extension is lost. For security reasons, users must provide an authentication code from a mobile device and approve via email before a new controller can be added using LUKSO's recovery service.
-- **Profile QR Import**: You can import any profile address into your extension. The import process will create a local controller key that needs to be signed off and added to the profile by one of your existing controllers with sufficient permissions. Within the new extension, you will receive a QR code of a transaction that can be scanned or copied. When received and executed by an existing extension, this new controller will gain permissions on the profile.
-- **File Export**: You can export the profile directly as a text file, including its private key, and store it somewhere safe. This private key will allow you to regain access to the original controller key.

 ## Can I add 2FA recovery to an existing Universal Profile?

 ## How to see and send assets from the Universal Profile?
 
-The Universal Profile Extension **does not directly manage token information**. Instead, it is designed to work with various decentralized applications (dApps) that can seamlessly integrate with your Universal Profile and interact with its information and controller keys. To see all your tokens, you can visit your profile on [UniversalProfile.cloud](https://universalprofile.cloud/). If you are logged in, you will also be able to transfer assets.

 ## How to get back funds from the extension's controller?
 
 There is currently no way to get back funds from the controller directly within the extension. If you want to pay for your transactions instead of using any Relay Service, we recommend only sending minimal LYX, e.g., `0.1 LYX`.
 
-However, as controller keys of your Universal Profile are regular wallet accounts, these can be imported into any other Ethereum wallet with custom network support. To get back funds from a controller, please open the Settings and reveal your private key of the related Extension controller.

 After you receive your private key, import this account to an Ethereum wallet with custom network support (e.g., MetaMask). Within the wallet, [add the LUKSO network](https://docs.lukso.tech/networks/mainnet/parameters#add-lukso-to-wallets) using the official network parameters. You will see the controller's funds after the network is added and selected. You can continue copying your Universal Profile's address and sending the LYX back. The imported account can be removed from the wallet after completing this process.
 
 ## How to use own LYX for Universal Profile transactions?
 
-To use your funds to send transactions from your Universal Profile, you must send LYX or LYXt to the extension's controller key. Sending it to the controller will ensure the transaction's Gas costs are funded. You can find the address of the extension's controller key within the permission section.

 ## “Universal Profile is not allowed by this Transaction Relay Service” Error
 
-If a user deploys a Universal Profile through a 3rd party with their own relayer (such as [_Universal.Page_](https://universal.page)), when importing the profile into the LUKSO Browser Extension, the LUKSO Relayer will not be compatible. Therefore, users should use a separate controller key that they can fund with some LYX.
+This error occurs if a user deployed his Universal Profile through a 3rd party platform that has its own Transaction Relay Service (like [_Universal.Page_](https://universal.page)). If the externally created profile gets imported into the Universal Profile Browser Extension, it is not compatible with LUKSO's own Transaction Relay Service.
+
+To **solve this issue**, users have to add a new controller to their Universal Profile. This controller must then be funded with LYX to execute transactions without any Transaction Relay Service. Within the transaction screen of the Universal Profile Extension, users can then define the controller they want to use.
