Hi so before it worked but now it says I need a passkey which I dont hasve... Is there other way to connect GAM?

You can usually choose another Google verification method. On Google's passkey screen, select Try another way and choose any other method Google offers for that account, such as a password or Google prompt. Composio connects Google Ads through Google's OAuth sign-in, so there isn't a separate Composio connection that can bypass this verification. If Try another way doesn't show a usable option, sign in from a trusted device or ask your Google Workspace admin to restore an available sign-in method, then reconnect Google Ads.
