+### 👁️ Biometrics manager
+
+`BiometricsManager` is used as an interface to Telegram's `WebApp.BiometricManager`. 
+It allows to store the encryption key inside secure storage on device, locked by a biometric lock.
+
+To get an instance of BiometricsManager, you should use the `useContext` hook:
+
+```ts
+import {BiometricsManagerContext} from "./biometrics";
+
+const biometricsManager = useContext(BiometricsManagerContext);
+```
+
+BiometricsManager is created using `BiometricsManagerProvider` component:
+
+> [!IMPORTANT]
+> BiometricsManagerProvider must be used inside the [SettingsManagerProvider](#-settings-manager)
+
+- `requestReason` is a message when user is prompted to provide necessary permissions
+- `authenticateReason` is a message shown to the user, when the key is requested
+
+```tsx
+import {BiometricsManagerProvider} from "./biometrics";
+
+<BiometricsManagerProvider requestReason="Allow access to biometrics to be able to decrypt your accounts"
+                           authenticateReason="Authenticate to decrypt your accounts">
+  ... rest of the app code ...
+</BiometricsManagerProvider>
+```
+
+#### isAvailable
+
+```ts
+isAvailable: boolean;
+```
+
+Boolean flag indicating whether biometric storage is available on the current device.
+
+#### isSaved
+
+```ts
+isSaved: boolean;
+```
+
+Boolean flag indicating whether the encryption key is saved inside the storage. 
+This flag is stored using the [`SettingsManager`](#-settings-manager).
+
+> [!NOTE]
+> Behaviour of this flag is different to `WebApp.BiometricManager.isBiometricTokenSaved`, as
+> in the current implementation `isBiometricTokenSaved` returns `true` even if a token is empty.  
+
+#### updateToken
+
+```ts
+updateToken(token: string): void;
+```
+
+This method saves the key inside secure storage. 
+It may ask the user for necessary permissions.
+To delete the stored key, pass empty string to the `token` parameter.
+
+#### getToken
+
+```ts
+getToken(callback: (token?: string) => void): void;
+```
+
+This method requests a token from the storage. If a request is successful, 
+the token is passed in the `token` parameter inside a callback. In case of a failure, 
+callback is called with empty `token`.
+
