+- `signal`: an abort signal to stop the iteration
+- `stopOnError`: wether to stop iteration of first error, or wait for all calls to finish and throw an `AggregateError`, defaults to `true`

+
+Or it can be used to replace the native implementation and speed up the whole app:
+
+```js
+// assign our cached implementation to dns.lookup
+const restore = createCachedLookup().patchGlobal()
+
+// to restore the previous implementation
+restore()
+```

+### Usual workflow
+
+> This section presents how this library should be used to implement a classic two factor authentification.
+
+#### Setup
+
+```js
+import { generateSecret, generateTotp } from '@vates/otp'
+import QrCode from 'qrcode'
+
+// Generates a secret that will be shared by both the service and the user:
+const secret = generateSecret()
+
+// Stores the secret in the service:
+await currentUser.saveOtpSecret(secret)
+
+// Generates an URI to present to the user
+const uri = generateTotpUri({ secret })
+
+// Generates the QR code from the URI to make it easily importable in Authy or Google Authenticator
+const qr = await QrCode.toDataURL(uri)
+```
+
+#### Authentication
+
+```js
+import { verifyTotp } from '@vates/otp'
+
+// Verifies a `token` entered by the user against a `secret` generated during setup.
+if (await verifyTotp(token, { secret })) {
+  console.log('authenticated!')
+}
+```
+
+### API
+
+#### Secret
+
+```js
+import { generateSecret } from '@vates/otp'
+
+const secret = generateSecret()
+// 'OJOKA65RY5FQQ2RYWVKD5Y3YG5CSHGYH'
+```
+
+#### HOTP
+
+> This is likely not what you want to use, see TOTP below instead.
+
+```js
+import { generateHotp, generateHotpUri, verifyHotp } from '@vates/otp'
+
+// a sequence number, see HOTP specification
+const counter = 0
+
+// generate a token
+//
+// optional params:

+//

+// 'otpauth://hotp/my%20app:account%20name?counter=0&issuer=my%20app&secret=OJOKA65RY5FQQ2RYWVKD5Y3YG5CSHGYH'
+```
+
+Optional params and their default values:
+
+- `digits = 6`: length of the token, avoid using it because not compatible with Google Authenticator
+
+#### TOTP

+```
+
+Optional params and their default values:
+
+- `digits = 6`: length of the token, avoid using it because not compatible with Google Authenticator
+- `period = 30`: number of seconds a token is valid
+- `timestamp = Date.now() / 1e3`: Unix timestamp, in seconds, when this token will be valid, default to now
+- `window = 1`: number of periods before and after `timestamp` for which the token is considered valid
+
+#### Verification from URI
+
+```js
+import { verifyFromUri } from '@vates/otp'
+
+// Verify the token using all the information contained in the URI
+const isValid = await verifyFromUri(token, uri)
+// true
+```

+```
+
+Optional params and their default values:
+
+- `digits = 6`: length of the token, avoid using it because not compatible with Google Authenticator
+- `period = 30`: number of seconds a token is valid
+- `timestamp = Date.now() / 1e3`: Unix timestamp, in seconds, when this token will be valid, default to now
+- `window = 1`: number of periods before and after `timestamp` for which the token is considered valid
+
+#### Verification from URI
+
+```js
+import { verifyFromUri } from '@vates/otp'
+
+// Verify the token using all the information contained in the URI
+const isValid = await verifyFromUri(token, uri)
+// true
+```

+the code.

+You may:
+
+- report any [issue](https://github.com/vatesfr/xen-orchestra/issues)
