Secure Remote Password (SRP) only available on the apps, or also through the browser?

On your webpage titled "What if 1Password gets hacked?" I can read:
"1Password on your device sends the 1Password server a series of puzzles. Once solved, these prove to the server that you know your account password and Secret Key without having to share them. Likewise, the server has to prove to your device that it holds the data you’re asking for. These puzzles are different every time the app connects to the server, so they can never be replicated by an outside observer."
Should I understand that SRP is not available when I access my data through my browser?
