-**Migrating from SQLite to MySQL**
+### Create database and user
 
-An easy way of migrating from SQLite to MySQL has been described in this [issue comment](https://github.com/dani-garcia/bitwarden_rs/issues/497#issuecomment-511827057). The steps are repeated below. Please, note that you are using this at your own risk and you are strongly advised to backup your installation and data!

 ```sql

-2. Create a new database user and grant rights to database:

+2a. Create a new database user and grant rights to database (MariaDB, MySQL versions before v8):
 ```sql
 CREATE USER 'bitwarden_rs'@'localhost' IDENTIFIED BY 'yourpassword';
 GRANT ALL ON `bitwarden_rs`.* TO 'bitwarden_rs'@'localhost';
 FLUSH PRIVILEGES;
 ```
+
+2b If you use MySQL v8.x you need to create the user like this:
+```sql
+-- Use this on MySQLv8 installations
+CREATE USER 'bitwarden_rs'@'localhost' IDENTIFIED WITH mysql_native_password BY 'yourpassword';
+GRANT ALL ON `bitwarden_rs`.* TO 'bitwarden_rs'@'localhost';
+FLUSH PRIVILEGES;
+```
+If you created the user already and want to change the password type:
+```sql
+-- Change password type from caching_sha2_password to native
+ALTER USER 'bitwarden_rs'@'localhost' IDENTIFIED WITH mysql_native_password BY 'yourpassword';
+```
+
 You might want to try a restricted set of grants:
 ```sql
-CREATE USER 'bitwarden_rs'@'localhost' IDENTIFIED BY 'yourpassword';
 GRANT ALTER, CREATE, DELETE, DROP, INDEX, INSERT, SELECT, UPDATE ON `bitwarden_rs`.* TO 'bitwarden_rs'@'localhost';
 FLUSH PRIVILEGES;
 ```
