What should I do if I forget my thinkphp login password?

ThinkPHP is a popular open source PHP web application development framework in China. Its efficiency and ease of use have a large number of users. However, sometimes we encounter some minor problems, such as forgetting the ThinkPHP login password. This is annoying, but not impossible.

1. Retrieve the administrator password

1. Method to retrieve the password

(1) Database retrieval

In the database Find the user table, search for the administrator's record, modify the password set for you in the password field, and then save it. Taking MySQL as an example, the search SQL statement is as follows:

SELECT * FROM admin WHERE username='admin';

Just change the password field in the query result to a new password.

(2) Code rewriting

If the database operation to retrieve the password cannot be implemented, the password can be retrieved through code rewriting. The following is a code example:

// Thinkphp 5.x
// 编辑后直接运行即可输出新密码
namespace app\index\controller;

use think\Controller;
use think\Db;

class Password extends Controller
{
    // 找回管理员密码
    public function index()
    {
        // 1.找到管理员的ID
        $admin_id = 1;
        // 2.设置新密码
        $new_password = '123456';
        // 3.查询密码加盐信息
        $user = Db::name('admin')->where('id',$admin_id)->find();
        if($user){
            // 4.加盐加密生成新密码
            $new_password_md5 = md5($new_password.$user['salt']);
            // 5.更新管理员密码
            Db::name('admin')->where('id',$admin_id)->update(['password'=>$new_password_md5]);
            echo '新密码：'.$new_password;
        }else{
            echo '管理员帐号不存在！';
        }
    }
}

2. Preventive measures

In order to improve security, we should take some preventive measures as much as possible, such as:

• Set complex passwords and avoid using simple Numbers, letters or consecutive symbols.
• Change the password regularly and ensure the security of the password when it is updated.
• Add management control measures such as verification codes and limiting the number of logins to reduce the possibility of being attacked.

2. Retrieve member password

1. Method to retrieve password

(1)Change the password directly

In the database, find the user table of the member, search for the user and directly modify the password field. The method is the same as modifying the administrator password.

(2) Password retrieval via email

Websites usually provide a password retrieval function to provide users with a service for retrieving forgotten passwords via email. When a user submits an application through the password retrieval function, the website will send a password reset email to the user's registered email address and provide a link to change the password in the email. The user can change the password voluntarily through the link. This method ensures the security of password retrieval and saves programmers time in changing passwords.

2. Preventive measures

Same as the administrator password precautions, strengthening password complexity is the most basic security precaution. In addition, it is recommended to provide the function of changing the password in the account settings, so that users can more conveniently handle it when they forget their password.

3. Summary

Forgetting your password is an inevitable little thing in daily life, but we should strengthen password prevention through various methods, increase the complexity of the password, and retrieve the password functions are set in appropriate locations. At the same time, website administrators must ensure the security of the database and prohibit changing passwords through SQL injection and other means to avoid being attacked by criminals.
