Abstract
A method for managing passwords for a user. A processor of an apparatus storing at least one received, incorrect password proposal receives via a user interface a further password proposal from a user; generates a hash value for the further password proposal; sends the hash value to the authentication server; receives from the authentication server a message indicative of whether the hash value corresponds to a correct password or to an incorrect password. In case the message indicates that the hash value corresponds to a correct password, the processor uses a distance function on each incorrect password proposal to obtain a distance value representative of a distance between the incorrect password proposal and the correct password; and sending to the authentication server hash values for password proposals for which the distance value is lower than or equal to a threshold value. Also provided are the apparatus and a computer program support. The disclosure can provide resistance to typing errors in the password proposals.
