VPN subscription URLs, keys and QR codes

How subscription links work, why credentials are sensitive and what an account dashboard displays.

How it works

A network subscription may provide one or more compatible connection profiles. An import URL can keep a client updated, while a QR code transfers configuration without manually typing a long string.

Application names do not define your service type: Happ, V2Ray-compatible clients and other apps work only with the formats they actually support.

What to keep in mind

Review expiration, device limits, data limits and subscription status in your account. Do not publish your URL: depending on the provider, a copy may grant access to your credentials.
