如何修改此powershell脚本以包含密码？

$password = Read-Host "请输入密码" -AsSecureString

$password = ConvertTo-SecureString "your_password_here" -AsPlainText -Force

$password = Get-Content "password.txt" | ConvertTo-SecureString -AsPlainText -Force

# 选择一种方法获取密码
$password = Read-Host "请输入密码" -AsSecureString

# 或者
# $password = ConvertTo-SecureString "your_password_here" -AsPlainText -Force

# 或者
# $password = Get-Content "password.txt" | ConvertTo-SecureLine -AsPlainText -Force

# 设置远程计算机的凭据
$credential = New-Object System.Management.Automation.PSCredential ("username", $password)

# 使用凭据连接到远程计算机
Invoke-Command -ComputerName "remote_computer_name" -Credential $credential -ScriptBlock {
    # 在此处添加要在远程计算机上执行的命令
}
