Oracle is a common database system, and data security is very important. Below we will introduce in detail how to set a password in Oracle database to protect your data.
- Log in to the database
First, log in to the Oracle database. You can use tools such as SQL*Plus or SQL Developer to log in to the database as an administrator by entering your username and password.
- Modify user password
In the Oracle database, you can use the ALTER USER statement to modify the user password. The syntax is as follows:
ALTER USER username IDENTIFIED BY new_password;
Among them, username is the username of the user who wants to change the password, and new_password is the new password.
For example, if you want to change the password of user test to mypassword, you can use the following command:
ALTER USER test IDENTIFIED BY mypassword;
- Confirm the password change
Once you After using the ALTER USER command to change the password, you should confirm that the password change has taken effect. You can use the following command to verify whether the new password is effective:
CONNECT username/new_password;
where username is the username of the user you want to log in, and new_password is the new password you just set.
For example, if you want to use the new password mypassword to log in to user test, you can use the following command:
CONNECT test/mypassword;
If the login is successful, the password change has taken effect. If you cannot log in, please check again whether the username and password are correct.
- Password Security Recommendations
Although setting up an Oracle password is relatively simple, in order to better protect your data, it is recommended to follow the following password security recommendations:
- Do not use simple passwords such as 123456 or password that are easy to guess;
- Use a strong password that is at least 8 characters long, including numbers, letters, and symbols;
- Do not use the same password on multiple websites or systems;
- Change your password regularly, it is recommended to change it every three months.
Summary
Setting a password in an Oracle database is very simple. However, to protect your data, we strongly recommend that you use a strong password and follow password security recommendations. Additionally, changing passwords regularly can further improve the security of your data.
