phpMyAdmin is often incompatible with the browser password manager due to the special login mechanism. It is mainly because its form sends credentials directly to the MySQL server rather than through the PHP backend processing, and the form action points to a non-standard URL, may use HTTP basic authentication, and lacks a clear login and successful jump mode. To improve compatibility, you can use bookmark scripts to automatically fill, switch to cookie authentication, use dedicated password management tools, and avoid using HTTP basic authentication. However, security risks need to be paid attention to, including credential leakage caused by forgery pages, improper session management, risk of brute force cracking on shared hosting, permission spread caused by configuration errors, and password reuse problems. Long-term recommendations are recommended to use strong passwords and restrict access to phpMyAdmin

To copy the database or table in phpMyAdmin, you can follow the following steps: 1. When copying the entire database, select the source database, click the "Operations" tab, fill in the new database name and select the copy content (structure and data, structure only or data only), and complete the copy after submission; 2. When copying a specific table, open the source table, enter the "Operations" tab, specify the new table name and target database in the "Copytableto" section (if necessary), select whether to copy the data, and click Go to perform the operation. Pay attention to ensuring that the target does not exist and has sufficient permissions, and pay attention to the need to manually handle views, stored procedures, etc.

To set the default character set for a new database or table in phpMyAdmin, you should first set the global default character set and collation rules by modifying the MySQL server configuration file. For example, add character-set-server=utf8mb4 and collation-server=utf8mb4_unicode_ci in /etc/my.cnf or C:\ProgramData\MySQL\MySQLServerX.Y\my.ini, and then restart the MySQL service; secondly, when creating a new database in phpMyAdmin, you should select the corresponding collation rules in the "Collation" drop-down menu.
