The invention provides a method of independently generating a dynamic password by a client and a server for subsequent verification of the generated password by either the server or the client. The method includes: registering a user ID for identification of the client; providing one or more static values and options to generate one or more variable values for the registered user ID; providing options to generate and apply instructions (e.g. mathematical, logical, locating, selection, or mixing-values operations); deriving a base value (e.g. a matrix, a phrase, text, numeric value, alphabets, characters, images, colours) by the server; applying the instructions on the one or more static value, the one or more variable value and the base value to generate the password; providing the generated password in the server by the client; generating a random password by the server and verifying the generated password with the random password generated by the client. Examples of static and variable values are numeric or alphanumeric values, date, century, year, month, week, season, rainbow, time or timestamp, age, measurements of distance, time, currency, weight, capacity, area, numbers or words or letters in a sentence or a captcha value. |
