'Reset MySQL root password using ALTER USER statement after install on Mac

I'm new to the whole Mac experience. I recently installed MySQL and it seems I have to reset the password after install. It won't let me do anything else.

Now I already reset the password the usual way:

update user set password = password('XXX') where user = root;

(BTW: took me ages to work out that MySQL for some bizarre reason has renamed the field 'password' to 'authentication_string'. I am quite upset about changes like that.)

Unfortunately it seems I need to change the password a different way that is unknown to me. Maybe someone here has already come across that problem?

If this is NOT your first time setting up the password, try this method:

mysql> UPDATE mysql.user SET Password=PASSWORD('your_new_password')
           WHERE User='root';

And if you get the following error, there is a high chance that you have never set your password before:

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

To set up your password for the first time:

mysql> SET PASSWORD = PASSWORD('your_new_password');
Query OK, 0 rows affected, 1 warning (0.01 sec)

If you started mysql using mysql -u root -p

Try ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

I have same problem on Mac

First, log in mysql with sandbox mode

mysql -u <user> -p --connect-expired-password

Then, set password

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('XXXX');

Query OK, 0 rows affected, 1 warning (0.01 sec)

It works for me ~

If you use MySQL 5.7.6 and later:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

If you use MySQL 5.7.5 and earlier:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

MySQL Documentation

Solution 5:^[5]

On MySQL 5.7.x you need to switch to native password to be able to change it, like:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'test';

Solution 6:^[6]

Run these:

$ cd /usr/local/mysql/bin
$ ./mysqladmin -u root password 'password'

Then run

./mysql -u root

It should log in. Now run FLUSH privileges;

Then exit the MySQL console and try logging in. If that doesn't work run these:

$ mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET authentication_string=PASSWORD("XXXXXXX") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit

Change xxxxxx to ur new password. Then try logging in again.

Update. See this http://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html

It should solve your problem.

If you are on oracle try this

ALTER USER username IDENTIFIED BY password

Solution 7:^[7]

UPDATE user SET authentication_string=PASSWORD("MyPassWord") WHERE User='root'; ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '("MyPassWord") WHERE User='root'' at line 1

Resolved with

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

Reference from below site

https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html

Solution 8:^[8]

Maybe try that ?

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('XXX');

SET PASSWORD FOR 'root'@'%' = PASSWORD('XXX');

Depending on which access you use.

(and not sure you should change yourself field names...)

https://dev.mysql.com/doc/refman/5.0/en/set-password.html

Solution 9:^[9]

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

Use this line...

Solution 10:^[10]

On Ver 14.14 Distrib 5.7.19, for macos10.12 (x86_64), I logged in as: mysql -uroot -p then typed in the generated password by MySQL when you install it. Then..

ALTER USER 'root'@'localhost' IDENTIFIED BY '<new_password>';

Example:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Ab1234'; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye $ mysql -uroot -p

And you can type in 'Ab1234'

Solution 11:^[11]

Mysql 5.7.24 get root first login

step 1: get password from log

 grep root@localhost /var/log/mysqld.log
    Output
        2019-01-17T09:58:34.459520Z 1 [Note] A temporary password is generated for root@localhost: wHkJHUxeR4)w

step 2: login with him to mysql

mysql -uroot -p'wHkJHUxeR4)w'

step 3: you put new root password

SET PASSWORD = PASSWORD('xxxxx');

you get ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

how fix it?

run this SET GLOBAL validate_password_policy=LOW;

Try Again SET PASSWORD = PASSWORD('xxxxx');

Solution 12:^[12]

This worked for me:

ALTER USER USER() IDENTIFIED BY 'auth_string';

I found it here: http://dev.mysql.com/doc/refman/5.7/en/alter-user.html#alter-user-current

Solution 13:^[13]

Here is the way works for me.

mysql> show databases ;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> uninstall plugin validate_password;

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> alter user 'root'@'localhost' identified by 'root';

Query OK, 0 rows affected (0.01 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.03 sec)

Solution 14:^[14]

When you use SET PASSWORD = PASSWORD('your_new_password'); it may crash for it

(ERROR 1819 (HY000): Your password does not satisfy the current policy requirements)

.you can use SET GLOBAL validate_password_policy=LOW; to slove it.

Solution 15:^[15]

in 5.7 version. 'password' field has been deleted. 'authentication_string' replace it

use mysql;
update user set authentication_string=password('123456') where user='root';
flush privileges;

Solution 16:^[16]

I also got the same problem in mac OS X 10.10.4(Yosemite).SET PASSWORD work for me.Alter password for mysql- mysql> SET PASSWORD = PASSWORD('your_password'); Query OK, 0 rows affected, 1 warning (0.01 sec)

set your Mysql environment path variable in .bash_profile and add the below line
export PATH=$PATH:/usr/local/mysql/bin, after that, run the following command :source .bash_profile

Solution 17:^[17]

Had the problem after I installed mysql workbench and mysql community server. Got generated password during the server installation. Double clicking on the exisiting local instance in workbench triggered a dialog where I could set the new password.

Solution 18:^[18]

mysql> SET PASSWORD = PASSWORD('your_new_password'); That works for me.

Solution 19:^[19]

remember versions 5.7.23 and up - the user table doesn't has column password instead authentication string so below works while resetting password for a user.

update user set authentication_string=password('root') where user='root';

Solution 20:^[20]

In mysql 5.7.x(replication) this issue can happen because the on the slave user either the password is unmatched or the root user does not exists on master.

For example(in my case):

I created an instance, altered password for the root and before replicating the slave, I dropped the root user. When I made the slave instance this alert appeared on the query: (because I altered the password on master before dropping the root user, and slave was reading from the first log which was actually an alter root user statement)

show slave status\G

So there are 2 solutions that can be applied here:

you can create root user on master host and slave host with same password
you can run the query on master hostreset master;

and reconnect slave to master.

Solution 21:^[21]

i had same problem. access denied..

so, my solution is,

go to

mysql> USE mysql;
mysql> SELECT User, Host, plugin FROM mysql.user;

you can see plug in column name

i changed plugin from unix_socket -> to mysql_native_password

so, type this

mysql > use mysql;
mysql> update user set plugin='mysql_native_password' where user='root';
mysql> flush privileges;

done. my version so 10.1.48 MariaDB ubuntu 18

Solution 22:^[22]

In order to chage user's password:

Firstly, login by root $sudo mysql
Change user's password

ALTER USER 'user'@'localhost' INDENTIFIED BY 'newPassword';
