FAQ
What is VAPID?
VAPID is a way for a server to identify itself to a push service. It lets you send push messages without having to use a service like Firebase. This is done with a public and private key pair.
Why do I need VAPID keys?
You need VAPID keys to send push notifications. The public key is used by the user's browser to sign up for your notifications, and the private key is used by your server to sign the push messages it sends. This makes sure the messages are from a trusted source.
Is it safe to generate VAPID keys in my browser?
Yes, it is safe to use this tool. It uses the secure Web Cryptography API to make the keys on your device. Your private key is never sent over the internet, so it stays private.
