Device, method, and graphical user interface for managing authentication credentials for user accounts

In one embodiment, when a new-password field is detected, the field is, without additional user input, automatically populated with a device-generated strong password. Affordances for accepting or declining use of the password are displayed. In one embodiment, when a one time use code is received via text or e-mail and a corresponding field is displayed, the code is presented as a suggested word for insertion via an insertion affordance. In one embodiment, a first device (e.g., a phone) receives an indication that a second device (e.g., a media player) is in need of authentication credentials. In response, the first device initiates a process for sharing the authentication credentials. In one embodiment, in response to a verbal request, password information is displayed by an electronic device. For example, "Show me my banking password" causes display of the relevant authentication credentials.
