You can try entering recovery and doing a wipe of the Cache Partition, see if that might help.Do you have the S7; similar issue have been reported with that device, after the update to MM. If the cache wipe through recovery won't help, I would suggest the below link to assist you in changing your password. If that won't help, then I'm afraid a factory reset is in order.
