blocks|key|2136665|text|显然，Moodle1.9.9版本只使用md5散列密码一次(根本没有盐！！)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2136666|因此，唯一要做的就是将admin行中的password字段替换为您希望应用md5的任何密码。|2136667|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Apparently Moodle version 1.9.9 only hashes the passwords with md5 once (with no salt at all!!).

So the only thing to do is to replace the in the admin row the password filed with whatever password you want with a md5 applied.

Currently Moodle introduces a salt in passwords to uniquely encrypt passwords in each installation.

If you didn't delete or changed guest account password you can copy its value to admin user password to be able to login.

Later you can change it to whatever you like.

User accounts are stored mdl_user table.

You could just check the sourcecode and see how the hash is calculated. You could then make a new hash with your new password with their hashing-function.

I checked the <a href="https://github.com/moodle/moodle/blob/a4d25731df2155e72abd2ea01136d69195e27724/auth/db/auth.php" rel="nofollow">source-code</a> and depending on the configuration, its hashed with md5 or sha1. So check your config and make a hash of your own.

<pre><code>// From the sourcecode:
if ($this-&gt;config-&gt;passtype === 'md5') { // Re-format password accordingly
 $extpassword = md5($extpassword);
} else if ($this-&gt;config-&gt;passtype === 'sha1') {
 $extpassword = sha1($extpassword);
}

In PHPMyAdmin, run the following query, substituting values as appropriate:

HOW TO CHANGE THE PASSWORD USING MD5 HASH:

<ol>
<li>Log into phpMyAdmin. cPanel hosting will have a database utility
called PhpMyAdmin within the cpanel. If the Moodle is installed on a
non cPanel hosting, contact the hosting company for information on
how to edit your database on the server. For more information on
logging into PhpMyAdmin, please see the article on "How do I manage
a MySQL database in PHPMyAdmin in my control panel (cpanel)?".</li>
<li>In PhpMyAdmin, find the table called mdl_user and select it. Since Moodle has many tables, the mdl_user table may be on the second page. Select the second page. Click the mdl_user table.</li>
<li>After selecting the table, find the table row for the user that is being edited. Click the Edit link with the pencil icon.</li>
<li>There will be a series of characters and numbers in the password field. This is an encrypted password so it cannot be viewed in the database. Replace the encrypted text with the new password for the login. </li>
<li>Next, in the drop down menu to the left, select MD5 then click Go. </li>
</ol>

This can also be done for the Email address and the Username. The Email and the Username do not need the MD5 hash.

You can reset any user password from command line. In your Moodle root:

<blockquote>
 php admin/cli/reset_password.php
</blockquote>

For dev prod environment you may also want to disable the password policy check (so you can enter a small and quick to type password). Edit reset_password.php and comment:

<blockquote>
 // if (!check_password_policy($password, $errmsg)) { 
 // cli_error($errmsg);
 
 // }

For Moodle 3.10.
Step 1
Create a temp PHP file in Moodle root directory to generate the password.
<pre><code>&lt;?php
include('config.php');
echo password_hash('new_password', PASSWORD_BCRYPT);
</code></pre>
Now run this php script to get the new password generated by the Moodle framework.
Step 2:
Open PHPMyAdmin and select the Moodle database.
Run this query.
<pre><code>update mdl_user set password=&quot;new_password_hash&quot; where username=&quot;admin&quot;;
</code></pre>
Step 3:
Delete the temp php script file from the Moodle root directory.

The password for an admin login in a moodle platform is lost.

I have access to the phpMyAdmin.

I went to the mdl_user table and there I can see or edit this table.

How should I proceed? Can I change the admin encripted password and secret key to a known password or is it simpler to just add an admin user? 

How would that be?

Manually change the moodle admin password with acces to phpMyAdmin or create another admin account?
