A registration of a user in a password strength management service is received. A list of social media accounts corresponding to the user and access credentials corresponding to each social media account in the list is received from the user. Social media information corresponding to the user is gathered from the social media accounts using the access credentials corresponding to each social media account in the list. In response to receiving an input of a new password string by the user, password strength of the new password string is evaluated in view of the gathered social media information corresponding to the user. ## Claims ### Claim 1 A method for providing an indication of user-tailored password strength, the method comprising: receiving a registration of a user in a password strength management service; receiving a list of social media accounts corresponding to the user and access credentials corresponding to each social media account in the list from the user; gathering social media information corresponding to the user from the social media accounts using the access credentials corresponding to each social media account in the list;
