What is the primary phone?
The primary phone is your trusted Wavo phone session. It can create or sign in to your account and can approve new computers. Wavo Web on a computer is a linked session, not a separate account.
WAVO WEB · HELP CENTERYour phone stays in control.
Your phone stays in control.
Your computers stay connected.
Wavo uses a phone-first device model. Your Android phone or iPhone is the primary place where you create your account, approve computers, review linked sessions and control how long each computer can use Wavo.

Why does Wavo work this way?
It reduces password exposure on shared or public computers. A computer receives access only after the signed-in phone approves the request. You can later pause, lock, rename, limit or sign out that computer from the phone.
How many computers can I link?
You can keep up to ten linked computer sessions active on one Wavo account. They can remain signed in at the same time unless you set an expiry, daily limit, temporary pause or permanent lock.
ACCOUNT SETUP
Create your Wavo account on a phone
Account creation is intentionally phone-only in this release.
Open Wavo on Android or iPhone
Visit Wavo from your phone. The registration form is served only to a phone browser. On a computer, Wavo shows the linked-device login instead.
Choose your permanent username
Your username is the identity people can use to find you. Choose it carefully and create a strong Wavo password.
Keep the phone signed in
This phone becomes a trusted primary-phone session and can approve future linked computers.
QR LINKING
Link a computer with the QR code
The QR code on Wavo Web stays valid for three minutes. A QR request can be used only for the browser that created it.
Open Wavo Web on the computer
The computer shows a large Wavo QR code and a a clean QR code with no visible countdown. Do not share a screenshot of this code.
Open Linked devices on your phone
On your signed-in primary phone, open the three-dot menu and choose Linked devices.
Verify on the phone
Wavo asks you to re-enter your Wavo password before the scanner opens. This prevents somebody holding an unlocked phone from silently adding a computer.
Scan, name and control the computer
Scan the QR, give the computer a recognizable name, optionally set an automatic sign-out time and choose a daily usage limit.
The computer opens automatically
When the phone approves it, Wavo Web finishes sign-in automatically. A hard refresh does not remove the linked session.
USERNAME CODE
Link without scanning a QR code
If the camera is unavailable, use an 8-character linking code.
6G7M–TMPQ
On the computer
Choose Login with username, enter your Wavo username and generate the code. The computer waits for approval from your phone.
On the phone
Open Linked devices, choose Enter linking code, verify your password and enter the eight characters shown on the computer.
Security rule
The code expires quickly and is tied to a single browser request. If it expires, generate a new code. Never send a linking code to another person.
DEVICE CONTROLS
Control every linked computer from your phone
Each linked computer has its own independent policy.
Rename the device
Use a name you recognize instantly, such as “Reception PC”, “Work laptop” or “Home desktop”.
Automatic sign-out
Set access to expire automatically. When the expiry is reached, the linked session is revoked and must be linked again.
Daily usage limit
Limit how many minutes the computer may actively use Wavo each UTC day. When the daily limit is reached, access is blocked until the next day.
Pause temporarily
Pause the computer for one hour or twenty-four hours. The session remains linked and can resume after the pause.
Lock completely
Lock a linked computer indefinitely. The browser stops receiving authenticated Wavo access until you unlock it from the phone.
Sign out remotely
Revoke a computer immediately. Its session token becomes unusable, even if the page is refreshed or reopened.
SECURITY MODEL
What Wavo protects during linking
A new QR login request is valid for three minutes while the computer is waiting. When it expires, Wavo shows a reload state; if you do nothing, a fresh QR appears automatically after 30 seconds.
The desktop request is bound to a browser fingerprint derived from server-observed browser details. A different browser cannot claim the same desktop request.
New computer approval requires a fresh Wavo-password verification on the primary phone.
After a browser claims an approved request, that request is marked claimed and cannot create another computer session.
Linked-device management APIs require a primary-phone session. Linked computer sessions are not permitted to use the device-control API.
Expiry, pause, permanent lock and daily-use limits are evaluated on authenticated requests, not only hidden in the interface.
About fingerprint / phone PIN verification
A normal website cannot directly read or validate your phone's operating-system PIN or fingerprint. Wavo currently uses server-side Wavo-password re-verification. Native device biometrics can be added securely through enrolled platform passkeys/WebAuthn or a native mobile application; simply detecting “fingerprint” from JavaScript would not be a secure substitute.
TROUBLESHOOTING
If the QR scanner does not link the computer
Try these checks in order.
The camera opens but does not detect the QR
Increase screen brightness on the computer, keep the whole QR inside the scan frame, move the phone slightly farther away, clean the phone camera lens, and avoid reflections. If the browser does not support automatic QR detection, use the 8-character linking code instead.
The QR says it expired
A Wavo Web QR stays valid for three minutes. When it expires, select the reload control to refresh it immediately, or wait 30 seconds and Wavo will generate a fresh QR automatically. If you already scanned successfully and are naming the device, Wavo gives the phone a short protected review window so the request does not disappear while you finish setup.
The computer stays on “Waiting for phone”
Confirm that the phone approved the same Wavo account. Keep both devices online. Wavo Web automatically retries its secure polling after temporary network errors and continues when the browser tab becomes visible again.
The computer was linked but I cannot see it on my phone
Open Linked devices and refresh the list. Only active linked-computer sessions appear. The list is loaded from server-side sessions, so it survives hard refreshes and browser restarts.
I reached the 10-device limit
Sign out or revoke one of the existing linked computers from your primary phone. Wavo does not silently replace an existing device when the account is already at the limit.
I paused or locked a computer by mistake
Open the device card on the phone. A temporary pause ends automatically, while a permanent lock stays in place until you choose Unlock device.

Keep your phone nearby. The QR method is the fastest option, and the username code is always available as a fallback.
