主　　题：password generation strategy password security mnemonic passwords 

摘      要：Identity authentication is the first line of defense for network *** have been the most widely used authentication method in recent *** there are security risks in passwords,they will be the primary method in the future due to their simplicity and low *** the security and usability of passwords,we propose AvoidPwd,which is a novel mnemonic password generation strategy that is based on keyboard *** helps users customize a“routeto bypass an“obstacleand choose the characters on the“routeas the final ***“obstacleis a certain word using any language and the keys adjacent to the“obstacleare typed with the“Shiftkey.A two-part experiment was conducted to examine the memorability and security of the AvoidPwd strategy with other three password strategies and three leaked password *** results showed that the passwords generated by the AvoidPwd strategy were more secure than the other leaked password ***,AvoidPwd outperformed the KbCg,SpIns,and Alphapwd in balancing security and *** addition,there are more symbols in the character distribution of AvoidPwd than the other *** is hopeful to solve the security problem that people are difficult to remember symbols and they tend to input letters and digits when creating passwords.
