One-Time Password

Uphold provides a TOTP (Time-Based One-Time Password) mechanism to secure user accounts. Adopting and adhering to this mechanism is recommended for safety reasons. The following section documents how the Authentication Methods API works to provide support for this security mechanism.

List Authentication Methods

curl https://api.uphold.com/v0/me/authentication_methods \
  -u <email>:<password>

The above command returns the following JSON:

[{
  "default": false,
  "id": "3f8f8264-2f5e-4b2b-8333-473715ab039a",
  "label": "Authenticator TOTP",
  "type": "totp",
  "verified": true,
  "verifiedAt": "2019-02-11T14:31:48.485Z"
},
{
  "default": true,
  "id": "be95ed5f-d048-4348-9572-411df23bedc9",
  "label": "+XXXXXXXXXX57",
  "type": "authy",
  "verified": true,
  "verifiedAt": "2019-01-11T14:20:04.055Z"
}]

Retrieves a list of authentication methods for the current user.

Request

GET https://api.uphold.com/v0/me/authentication_methods

Add Authentication Method

curl https://api.uphold.com/v0/me/authentication_methods/totp \
  -X POST \
  -H "Authorization: Bearer <token>" \
  -H 'OTP-Token: <OTP-Token>'

The above command returns the following JSON:

{
  "default": false,
  "id": "3f8f8264-2f5e-4b2b-8333-473715ab039a",
  "label": "Authenticator TOTP",
  "type": "totp",
  "url": "otpauth:https://totp/Uphold:[email protected]?algorithm=SHA1&digits=6&issuer=Uphold&period=30&secret=QRV62S3O6LXDB7FRKR4LMF3VGR6MZT7S",
  "verified": false,
  "verifiedAt": null
}

Request

POST https://api.uphold.com/v0/me/authentication_methods/totp

Requires the OTP-Token header with a valid TOTP token.

Response

Returns a fully formed Authentication Method representing the authentication method created.

Verify Authentication Method

curl https://api.uphold.com/v0/me/authentication_methods/3f8f8264-2f5e-4b2b-8333-473715ab039a/verify \
  -X POST \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{ "token": "<OTP-Token>" }'

The above command returns the following JSON:

{
  "default": false,
  "id": "3f8f8264-2f5e-4b2b-8333-473715ab039a",
  "label": "Authenticator TOTP",
  "type": "totp",
  "verified": true,
  "verifiedAt": "2019-02-11T14:31:48.485Z"
}

Request

POST https://api.uphold.com/v0/me/authentication_methods/:id/verify

Response

Returns an Authentication Method object representing the verified authentication method.

Remove Authentication Method

curl https://api.uphold.com/v0/me/authentication_methods/3f8f8264-2f5e-4b2b-8333-473715ab039a \
  -X DELETE \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -H "OTP-Token: <OTP-Token>"

The above command does not return a JSON response.

Request

DELETE https://api.uphold.com/v0/me/authentication_methods/3f8f8264-2f5e-4b2b-8333-473715ab039a

Requires the OTP-Token header to be sent with a valid TOTP token. You cannot delete all of a user's authentication methods as trying to delete the last verified method of a user will return an error.

Response

Returns an HTTP status code of 204 and no JSON body, in case of success.
