This credential is a security mechanism that allows our app to verify that the person accessing the cloud service is using an authorised device. As part of the onboarding process, each user chooses a second means of authentication for logging into the app (the first means of authentication is the credential stored on their phone). The options presented to the user will depend on the options supported by their mobile phone. These include a passcode, or a biometric logon such as a fingerprint or facial recognition. The value of FIDO authentication is that it provides a high level of security while being very simple to use. Each invited person chooses a means of logging into the app, which they are already familiar with because they already use this to unlock their mobile phone (e.g. a PIN, passcode or fingerprint). FIDO’s main purpose is to provide a secure and simple means of authenticating from a mobile app to internet-based servers. They particularly wanted to remove the need for people to use passwords on the web, as weak or hacked passwords are known to be a major reason for security breaches. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://help.security.gallagher.com/smb/smb-app/help-resources/fido-authentication.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
