Registration
Creating a Zexa account takes just a few minutes. Have your company NIF or personal Bilhete de Identidade handy before you begin.1
Visit the sign-up page
Open https://app.zexa.ao/signup in your browser.
2
Enter your identification details
In the Tax / Identity Number field, enter either your company NIF (for a business account) or your Bilhete de Identidade (BI) number (for a personal account).
A company NIF must be a valid Angolan tax identification number issued by the Agência Geral Tributária (AGT). If you’re registering as an individual rather than a business, you can use your Bilhete de Identidade number instead.
3
Fill in your contact details
Enter your email address and a phone number that can receive SMS verification codes. Both will be used for account notifications and security purposes.
4
Choose a password
Create a strong password of at least 8 characters, mixing uppercase letters, lowercase letters, numbers, and symbols.
5
Accept the terms and create your account
Read and accept the Terms of Service and Privacy Policy, then click Create Account. Zexa sends a confirmation email to the address you provided — click the verification link in that email to activate your account.
Two-Factor Authentication (2FA)
Two-factor authentication adds a second layer of security to your login. Zexa strongly recommends enabling it on all accounts, especially those with admin privileges.1
Open Security settings
Log in to https://app.zexa.ao, then navigate to Settings → Security.
2
Enable 2FA
Click Enable Two-Factor Authentication. Zexa displays a QR code — scan it with an authenticator app such as Google Authenticator, Authy, or any TOTP-compatible app.
3
Confirm the setup
Enter the 6-digit code generated by your authenticator app into the confirmation field and click Verify. Once verified, 2FA is active on your account.
4
Save your backup codes
Zexa generates a set of single-use backup codes after you enable 2FA.
Invite Team Members
Zexa supports role-based access control (RBAC) so you can give teammates the level of access they need without exposing sensitive settings. There are two built-in roles:
To invite a team member:
1
Go to Team settings
In the dashboard, navigate to Settings → Team.
2
Send an invitation
Click Invite Member, enter the person’s email address, select their role (Admin or Member), and click Send Invite. They receive an email with a link to join your Zexa workspace.
3
Manage existing members
From the same Settings → Team page you can change a member’s role or remove them from your workspace at any time.
Verify Your Sender ID
Before you can send SMS or WhatsApp messages, you must register a Sender ID and wait for it to be approved. A Sender ID is the name or number your recipients see in the From field — for example,MyBrand or +244900000000.
Unregistered Sender IDs are blocked by mobile operators and the WhatsApp Business API. Registering yours in advance ensures your messages are delivered without interruption.
1
Navigate to Sender IDs
In the dashboard, go to Messaging → Sender IDs.
2
Submit a new Sender ID
Click Register Sender ID, fill in the requested details (name, channel, use-case description), and submit the form. Zexa reviews the request and notifies you by email once it is approved or if additional information is needed.
Approval times vary by channel and may take up to 3 business days. You can continue setting up your account and testing other features while your Sender ID is under review.
