Can i change the root password after rooting my android device by simply typing «passwd»?

Android does not use /etc/passwd so it also does not have passwd program.

how is the rooting process working ? i mean what is the «one click root» apps doing to my phone?

I’m not quire sure with the exact process myself, you probably want to ask to rooting developers. However, my guess is it just reverts the security check that originally prevent developer from setuid 0.

And im a developer, so how can i find hidden APIs (like iOS) for rooted app development ?

Since Android is open source, there is no truly hidden API in Android. However, there are some unpublicized or undocumented APIs, you can browse for this in Android’s source code. However, these APIs are not about root developments, they’re usually in-development APIs that are not ready yet or is too localized for specific purpose that is not useful for public developer (or perhaps Google just haven’t realized their usefulness yet). You are not restricted from using these APIs, but since these are not an officially supported APIs, they may disappear or break backward compatibilities in the future. If you need to use these APIs make sure your app breaks gracefully.

What is the default root password for raspbian jessie or debian 9?

I have Raspbian Jessie stretch iso «Raspberry Pi Desktop» or pixel Virtualbox and I need to install keys with root «su», what is the default password since raspberry nor pi aren’t working.

You are in emergency mode. After logging in, type «journalctl -xb» to view
system logs, «systemctl reboot» to reboot, «systemctl default» or ^D to
try again to boot into default mode.

In raspbian, you can reset the root password:

sudo passwd root

Then, the console write:

New password:

Write a password for root and then, the console write:

Retype the new password:

You must write the password you decided. If there is no errors you have this console message:

passwd: password updated successfully

Now the password is reset.

If you login into root with a GUI, press Ctrl+Alt+Del for disconnect beacause you don’t have taskbar.

Restart MySQL in passwordless mode, reset the password, restart the MySQL service.

# 1 : Stop mysql service
/etc/init.d/mysql stop
# 2: Start to MySQL server w/o password:
mysqld_safe --skip-grant-tables &
# Step # 3: Connect to mysql server using mysql client:
mysql -u root
-- 4: Setup new MySQL root user password
use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit
# 5: Stop MySQL Server:
/etc/init.d/mysql stop
# 6: Start MySQL server and test it

Find your socket file by running.

sudo find / -type s

create a link to this file in tmp directory.

sudo ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

$ mysql -u root

This worked for me. Now you should be able to go about your mysql business as usual, as I was.

There’s so many answers out there saying to reinstall mysql or use some combo of

mysqld_safe --skip-grant-tables

and / or

UPDATE mysql.user SET Password=PASSWORD('password')

Here’s what worked for me, on Ubuntu 18.04, from the top

$ sudo apt install mysql-server
$ sudo cat /etc/mysql/debian.cnf

Note the lines which read:

user     = debian-sys-maint
password = blahblahblah
$ mysql -u debian-sys-maint -p
Enter password: // type 'blahblahblah', ie. password from debian.cnf

mysql> USE mysql
mysql> SELECT User, Host, plugin FROM mysql.user;
+------------------+-----------+-----------------------+
| User             | Host      | plugin                |
+------------------+-----------+-----------------------+
| root             | localhost | auth_socket           |
| mysql.session    | localhost | mysql_native_password |
| mysql.sys        | localhost | mysql_native_password |
| debian-sys-maint | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
4 rows in set (0.00 sec)

mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root';
mysql> COMMIT;  // When you don't have auto-commit switched on
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
// For MySQL 5.7+
UPDATE mysql.user SET authentication_string=PASSWORD('new_password') where user='root';
mysql> FLUSH PRIVILEGES;
mysql> COMMIT;  // When you don't have auto-commit switched on
mysql> EXIT

$ sudo service mysql restart
$ mysql -u root -p
Enter password: // Yay! 'new_password' now works!

After you installed MySQL-community-server 5.7 from fresh on linux, you will need to find the temporary password from /var/log/mysqld.log to login as root.

  1. grep 'temporary password' /var/log/mysqld.log
  2. Run mysql_secure_installation to change new password

MySQL 5.7 changed the secure model: now MySQL root login requires a sudo

1. Connect to mysql

sudo mysql --user=root mysql
CREATE USER 'phpmyadmin'@'localhost' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'phpmyadmin'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;

MySQL server 5.7 was already installed by default on my new Linux Mint 19.

But, what’s the MySQL root password? It turns out that:

The default installation uses auth_socket for authentication, in lieu of passwords!

sudo mysql --user=root
mysql> CREATE USER 'me'@'localhost' IDENTIFIED BY 'my_new_password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'me'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

Comparing «me» with «root»:

mysql> SELECT user, plugin, HEX(authentication_string)  FROM mysql.user WHERE user = 'me' or user = 'root';
+------+-----------------------+----------------------------------------------------------------------------+
| user | plugin                | HEX(authentication_string)                                                 |
+------+-----------------------+----------------------------------------------------------------------------+
| root | auth_socket           |                                                                            |
| me   | mysql_native_password | 2A393846353030304545453239394634323734333139354241344642413245373537313... |
+------+-----------------------+----------------------------------------------------------------------------+
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'SOME_NEW_ROOT_PASSWORD';

A good explanation.

None of these answers worked for me on Ubuntu Server 18.04.1 and MySQL 5.7.23. I spent a bunch of time trying and failing at setting the password and auth plugin manually, finding the password in logs (it’s not there), etc.

The solution is actually super easy:

sudo mysql_secure_installation

It’s really important to do this with sudo. If you try without elevation, you’ll be asked for the root password, which you obviously don’t have.

quit;
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

Sometimes, even after typed in the terminal

mkdir -p /var/run/mysqld
chown mysql:mysql /var/run/mysqld
/etc/init.d/mysql stop
mysqld_safe --skip-grant-tables &

I got the error that the mysqld don’t exists. So, quit, and type the same commands again.

And the final command

sudo /etc/init.d/mysql start

Sometimes doesn’t work. Only after restart the computer.

I just installed Linux Mint 19 (based on Ubuntu 18.04) on my machine. I installed MySQL 5.7 from the repo (sudo apt install mysql-server) and surprisingly during installation, the setup didn’t prompt to enter root password. As a result I wasn’t able to login into MySQL. I googled here and there and tried various answers I found on the net, including the accepted answer above. I uninstalled (purging all dpkgs with mysql in its name) and reinstalled again from the default Linux Mint repositories. NONE works.

After hours of unproductive works, I decided to reinstall MySQL from the official page. I opened MySQL download page (https://dev.mysql.com/downloads/repo/apt) for apt repo and clicked Download button at the bottom right.

Next, run it with dpkg:

sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb

At the installation setup, choose the MySQL version that you’d like to install. The default option is 8.0 but I changed it to 5.7. Click OK to quit. After this, you have a new MySQL repo in your Software Sources.

Update your repo:

sudo apt update

Finally, install MySQL:

sudo apt install mysql-server

And now I was prompted to provide root password! Hope it helps for others with this same experience.

As of Ubuntu 20.04 with MySql 8.0 : you can set the password that way:

  1. login to mysql with sudo mysql -u root

  2. change the password:

USE mysql;
UPDATE user set authentication_string=NULL where User='root';
FLUSH privileges;
ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'My-N7w_And.5ecure-P@s5w0rd';
FLUSH privileges;
QUIT

To do it in non interactive mode (from a script):

systemctl start mysqld
MYSQL_ROOT_TMP_PSW=$(grep 'temporary password' $logpath/mysqld.log |sed "s|.*: ||")

## POPULATE SCHEMAS WITH ROOT USER
/usr/bin/mysql --connect-expired-password -u root -p${MYSQL_ROOT_TMP_PSW} < "$mysql_init_script"

Here’s the head of the init script

SET GLOBAL validate_password_policy=LOW;
FLUSH privileges;

SET PASSWORD = PASSWORD('MYSQL_ROOT_PSW');
FLUSH privileges;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
FLUSH privileges;

...

Then restart the service systemctl restart mysqld

In my case the data directory was automatically initialized with the --initialize-insecure option. So /var/log/mysql/error.log does not contain a temporary password but:

What worked was:

shell> mysql -u root --skip-password
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
