Use the unique external ID created during passkey registration to retrieve a user's passkey devices from the Passage database. Learn more about external identifier.

Backend
app.get('/user/devices', async (req: Request, res: Response) => {
 
    // ... Verify user identity
 
    let user = User.findOne({id: req.session.id})
 
    let passkeys: WebAuthnDevices [] = [];
 
    // Verify that the Passage ID you created and stored is present
    // This indicates that the user has passkeys
    if(user.passageExternalId !== null) {
 
        // Retrieve a list of all devices used to register a passkey
        passkeys = await passage.getDevices(user.passageExternalId!);
    }
 
    return res.status(200).json({username, passkeys}).end();
});
