11. User Activation

Reference: {#RefActivation}

Author: Artyom Kazak

A user is called activated they have a verified identity – e.g. a phone number that has been verified via a text message, or an email address that has been verified by sending an activation code to it.

A user that has been provisioned via single sign-on is always considered to be activated.

11.1. Activated vs. non-activated users

Non-activated users can not connect to others, nor can connection requests be made to anonymous accounts from verified accounts. As a result:

  • A non-activated user cannot add other users to conversations. The only way to participate in a conversation is to either create a new conversation with link access or to use a link provided by another user.

The only flow where it makes sense for non-activated users to exist is the wireless flow used for guest rooms

11.2. API

11.2.1. Requesting an activation code

During the standard registration flow, the user submits an email address or phone number by making a request to POST /activate/send. A six-digit activation code will be sent to that email address / phone number. Sample request and response:

POST /activate/send

    // Either 'email' or 'phone'
    "phone": "+1234567890"
200 OK

The user can submit the activation code during registration to prove that they own the email address / phone number.

The same POST /activate/send endpoint can be used to re-request an activation code. Please use this ability sparingly! To avoid unnecessary activation code requests, users should be warned that it might take up to a few minutes for an email or text message to arrive.

11.2.2. Activating an existing account

If the account has not been activated during verification, it can be activated afterwards by submitting an activation code to POST /activate. Sample request and response:

POST /activate

    // One of 'phone', 'email', or 'key'
    "phone": "+1234567890",

    // 6-digit activation code
    "code": "123456",

    // Verify the 'code' but don't activate the account (the 3-attempt limit
    // on failed verification attempts still applies)
    "dryrun": false
200 OK

    "phone": "+1234567890",

    // Whether it is the first successful activation for the user
    "first": true

If the email or phone has been verified already, POST /activate will return status code 204 No Content. If the code is invalid, POST /activate will return status code 404 Not Found with "label": "invalid-code".

There is a maximum of 3 activation attempts per activation code. On the third failed attempt the code is invalidated and a new one must be requested.

11.2.3. Activation event

When the user becomes activated, they receive an event:

    "type": "user.activate",
    "user": <self profile>

11.2.4. Detecting activation in the self profile

In addition to the activation event, activation can be detected by polling the self profile:

GET /self

    "accent_id": 0,
    "assets": [],
    "email": "pink@example.com",
    "id": "2f7e582b-9d99-4d50-bbb0-e659d63491d9",
    "locale": "en",
    "managed_by": "wire",
    "name": "Pink",
    "picture": []

If the profile includes "email" or "phone", the account is activated.

11.3. Automating activation via email

Our email verification messages contain headers that can be used to automate the activation process.

An email caused by POST /activate/send will contain this set of headers:

X-Zeta-Purpose: Verification
X-Zeta-Code: 123456

An email caused by POST /register will contain this set of headers (the opaque "key" might be used instead of "email" in the POST /activate request):

X-Zeta-Purpose: Activation
X-Zeta-Key: ...
X-Zeta-Code: 123456

11.4. Phone/email whitelist

The backend can be configured to only allow specific phone number prefixes and email address domains to register. The following options have to be set in brig.yaml:

    - wire.com
    - example.com
    - notagoodexample.com
    - "+49"
    - "+1555555"

When those options are present, the backend will match every activation request against these lists.

If an email address or phone number are rejected by the whitelist, POST /activate/send or POST /register will return 403 Forbidden:

    "code": 403,
    "label": "unauthorized",
    "message": "Unauthorized e-mail address or phone number."
