Login, OTP & Sessions
Volt desktop will not log in
Check whether WhatsApp Web is open in a browser for the same phone number. Running both at the same time can cause a session conflict. Log out of WhatsApp Web, then try Volt again.
The OTP never arrives or the login modal loops
Do not reload repeatedly. Repeated attempts can trigger a Meta rate limit.
- Reload once.
- Wait for the verification attempt to complete.
- If WhatsApp is experiencing an incident, wait until service recovers before trying again. You can check Meta Status .
Volt is stuck on the loading screen
Initial event synchronization can take several minutes after an update or after Volt has been closed for several days. Wait a few minutes before restarting.
If the screen does not progress, fully quit Volt with Cmd+Q on macOS or close it completely on Windows, then reopen it.
Use two WhatsApp numbers
Volt supports one WhatsApp account per app instance. To use two numbers in parallel, run one in the desktop app and the other in the Chrome extension or a separate browser profile.
A high-volume action forced a logout
WhatsApp can force a connected session to log out after unusually rapid or high-volume activity. Log in again, then reduce the size and speed of bulk actions. See Broadcast for responsible-use guidance.
