Frequently asked questions
Where do I get a Happ VPN key?
In the Telegram bot: activate the trial or a subscription and get your personal subscription link to add to the Happ app.

My key doesn't work — what now?
Check validity, refresh the config, switch server and restart the app; get a new key if needed.
Can I share my key?
The key is tied to your subscription and device limit; sharing may exceed connection limits.
