Magento – You did not sign in correctly or your account is temporarily disabled

After some search on the internet, I found that due to security reasons Magento has introduced account disabled functionality with considering the security of the business.

Here is how you can unlock and Go to your Magento root folder via SSH/PUTTY

Then Run following command

php bin/magento admin:user:unlock ADMINUSERNAME

Or jump into bin directory from Magento root: cd bin/

and then run the command

php magento admin:user:unlock ADMINUSERNAME

For Reference, check here http://devdocs.magento.com/guides/v2.0/install-gde/install/cli/install-cli-subcommands-admin.html

Did you set the permissions while being logged in as root? Which user is your apache running with? If www-data is the user apache is using, it doesn't seem to have necessary permissions on var.

If it's just your local installation, you can do the following as root user in apache basedir:

chmod uog+rwx var pub/static pub/media
chown www-data:www-data var pub/static pub/media

This makes the necessary folders globally accessible. For the second line you need to know the user apache is running with. The example above is the default setting of apache. Don't use these settings in production.
