Password generation using SHA256

Can we generate password by selecting a simple password and taking a SHA256 Hash of that. Then take first 10 characters of that hash and add some symbols to generate a password.

Thus, you don’t have to remember the password, you can generate it on the fly.

Can anyone tell me what would the disadvantages would be?

you could, better than nothing.

HOWEVER, the attack would be done by attacking the base password and regenerate the possibles haches, and not directly the hash.

If you use the password “password”, that password being in any password list, the hash produced will easily be found.
