This is the reference pages I found when I googled : 
<a href="https://dev.mysql.com/doc/refman/5.5/en/set-password.html" rel="noreferrer">Link1</a> and 
<a href="http://dev.mysql.com/doc/refman/5.6/en/user-names.html" rel="noreferrer">Link2</a>

<blockquote>
 If you are using MySQL Replication, be aware that, currently, a
 password used by a replication slave as part of a CHANGE MASTER TO
 statement is effectively limited to 32 characters in length; if the
 password is longer, any excess characters are truncated. This is not
 due to any limit imposed by the MySQL Server generally, but rather is
 an issue specific to MySQL Replication. (For more information, see <a href="https://bugs.mysql.com/bug.php?id=43439" rel="noreferrer">Bug 43439</a>.)
</blockquote>

Fix documented in the <a href="https://dev.mysql.com/doc/relnotes/mysql/5.7/en/news-5-7-5.html" rel="noreferrer">5.7.5 changelog</a>, as follows:

<blockquote>
 The maximum length that can be used for the password in a CHANGE
 MASTER TO statement is 32 characters. Previously, when a longer
 password was employed, any excess length was silently truncated
 by the server. Now when the password's length exceeds 32
 characters, CHANGE MASTER TO fails with an error.
</blockquote>

So I would safely assume my password should not be more than 32 characters.

This may not fully answer &quot;what is maximum MySQL pwd length...&quot;, but I can tell you my recent findings.
-- installing in Windows 10: &quot;Server version: 8.0.24 MySQL Community Server - GPL &quot;
-- Server, Workbench, documentation, all installed without error.
-- Post-install could not connect as root, getting &quot;Access denied for user 'root'@'localhost' (using password yes)&quot;, as well as CLI would close immediately after entering password and pressing Enter.
-- Tried several solutions from web, then it occurred to me it may be root password, my understanding was it is 32 characters max.
-- Maybe it's not max 32 characters. On the 4th install attempt, only change was I replaced the 32 character root password with a new 30 character password, and it all works now. No other changes in the install process.
-- If it really is 32 characters max, then maybe there is truncation occurring, or maybe MySQL was not happy with one or more of the 32 characters in original root password, but then again, test connection worked and no errors during install.

What is the maximum length for a MySQL user password?

MySQL uses <a href="http://dev.mysql.com/doc/refman/5.1/en/encryption-functions.html#function_password" rel="noreferrer"><code>PASSWORD(str)</code></a> to encrypt the cleartext password <code>str</code>. This hashed password string is stored in the <code>mysql.user</code> grant table with a <code>CHAR(41)</code> datatype. 

However, I was not able to find what is the maximum length for the cleartext password <code>str</code>, if there is one. Can anyone help?
