当使用AWS Cognito的FORCE_CHANGE_PASSWORD选项时，并且email_verified为true时，用户将收到一封包含临时密码的电子邮件。然而，使用此临时密码登录后会出现“无法使用临时密码登录”的错误消息。此错误是由于Cognito设置了需要新密码，以确保安全性。以下是一个示例代码片段，可以在用户登录时捕获此错误并将新密码发送到Cognito：

try:
    response = client.initiate_auth(
        AuthFlow='USER_PASSWORD_AUTH',
        AuthParameters={
            'USERNAME': username,
            'PASSWORD': password,
        },
        ClientId='1234567890123'
    )
    # Successful login
except botocore.exceptions.ClientError as error:
    if error.response['Error']['Code'] == 'NotAuthorizedException' and error.response['Error']['Message'] == 'User password has expired':
        # User needs to set new password
        try:
            response = client.admin_set_user_password(
                UserPoolId='us-west-2_abcdefghi',
                Username=username,
                Password=new_password,
                Permanent=True
            )
            # New password set successfully
        except botocore.exceptions.ClientError as error:
            # Error setting new password
            print(error)
    else:
        # Other login error
        print(error)
