With the newest hardware (CPU and GPU) improvements it is become possible to decrypt SHA256 algorithm back. So it is no longer recommended to use it for password protection or other similar use cases. Some years ago you would protect your passwords from hackers by storing SHA256 encrypted password in the your data base. This is no longer a case.
SHA256 algorithm can be still used for making sure you acquired the same data as the original one. For example if you download something you can easily check if data has not changed due to network errors or malware injection. You can compare hashes of your file and original one which is usually provided in the website you are getting data or the file from.
