Each line needs to be configured to use the local password database:-

sw-1(config)#line vty 0 4
sw-1(config-line)#login local

sw-1(config)#ip ssh version 2
crypto key generate rsa modulus 2048
ip ssh time-out 60  
ip ssh authentication-retries 3 

See also ssh to Cisco 3750 for resolving issues with cyphers and hashs.

See ssh to Cisco 3750 to see how to edit your ~/.ssh/config file to fix this.
