Systems and methods for facilitating passkey login to a web domain

A system comprising:

• at least one hardware processor;
• and
• at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
• receive an identifier associated with a browser application executing on a client device that is used to access a webpage of a web domain;
• determine, based on the identifier, that a passkey for the web domain is likely to be accessible by the browser application at the client device;
• and
• responsive to determining that the passkey for the web domain is likely to be accessible by the browser application at the client device, cause the browser application to display a control to log in to an account at the web domain using the passkey.

A non-transitory computer readable storage medium storing executable instructions, execution of which by a processor causing the processor to:

• receive, at a server for a web domain, an identifier associated with a browser application executing on a client device that is used to access a webpage of the web domain;
• determine by the server, based on the identifier, that a passkey for the web domain is likely to be accessible by the browser application at the client device;
• and
• responsive to determining that the passkey for the web domain is likely to be accessible by the browser application at the client device, cause the browser application to display a control to log in to an account at the web domain using the passkey.
