How anonymous messages work on Snapchat
Snapchat itself always shows who sent a chat. Anonymous messages come from a separate link that you attach to a snap. When a friend taps it, a web page opens where they can type a message, and that message arrives in your anonymous inbox — not in Snapchat chat — with no name attached.
You do not need to connect any account or give an app access to Snapchat. The link is just a web address, which also means it works the same on Instagram and WhatsApp.
