How can I get access to the device with password to adb?

[TheZ3ro]

can you send a screenshot or describe better how do you connect with a user and password? this is not a common type of authentication in adb.
also if you could intercept USB or TCP communication with Wireshark would greatly help.

Thanks for your reply. This device can connect with password like this.

Using user as 'root', and password as 'oelinux123'.

what if you use adb_shell like this?

from adb_shell.adb_device import AdbDeviceUsb
from adb_shell.auth.sign_pythonrsa import PythonRSASigner

# Load the public and private keys
adbkey = 'path/to/adbkey'
with open(adbkey) as f:
    priv = f.read()
with open(adbkey + '.pub') as f:
     pub = f.read()
signer = PythonRSASigner(pub, priv)

# Connect via USB (package must be installed via `pip install adb-shell[usb])`
device = AdbDeviceUsb()
device.connect(rsa_keys=[signer], auth_timeout_s=0.1)

# Send a shell command
login = 'root\noelinux123\n'
response = device.shell(login + 'whoami')

Thank you . I try it, but doesn't work.
Since I don't have adbkey, I use the function below
device = AdbDeviceTcp('127.0.0.1', 5037, default_transport_timeout_s=9.) device.connect(auth_timeout_s=0.1) login = 'root\noelinux123\n' response = device.shell(login + 'whoami')
But cannot connect.

I use this method and it works, but some command like 'ls' or 'sqlite3' doesn't support.
` def adb_connect(self):
# 连接设备
self.child = pexpect.popen_spawn.PopenSpawn('adb shell')

    # 匹配提示符，输入用户名和密码
    self.child.expect(['#', ' $', 'mdm9607 login:'], timeout=3)
    self.adb_out.insertPlainText('检测到登录请求...\n')
    self.child.sendline('root')
    self.adb_out.insertPlainText('发送root用户名...\n')
    time.sleep(1)
    self.child.expect(['#', ' $', 'Password:'], timeout=4)
    self.adb_out.insertPlainText('检测到密码请求...\n')
    self.child.send('oelinux123\n')
    self.adb_out.insertPlainText('输入密码...\n')
    self.child.expect(['#', '~'], timeout=3)
    self.adb_out.insertPlainText('登录成功\n')`
