Symptoms
The Security Guide documentation explains that special characters are allowed in user's passwords, including the ampersand (&) character.
19c doc: https://docs.oracle.com/en/database/oracle/oracle-database/19/dbseg/configuring-authentication.html#GUID-1168CD4D-659E-432D-9CB7-F5733129657D
"These special characters are as follows: ‘ ~ ! @ # $ % ^ & * ( ) _ - + = { } [ ] \ / < > , . ; ? ' : | (space)"
Note "Doc ID 2220631.1" also explains, "As long we wrap your password in double quotes, password can include any character. Except double quotes themselves"
However, even with double quotes some documented special characters can not be used as it will prompt you for a value.
Examples:
SQL> alter user ken identified by "VZ38/>{SP&Ro{y9PKD&LMkuooUWYwJ";
Enter value for ro: ^C
SQL> alter user ken identified by "VZ38/>SPRo{y9PKDLMkuooUWYwJ";
User altered.
SQL> alter user ken identified by "VZ38/>SPRo{y9PKD&LMkuooUWYwJ";
Enter value for lmkuoouwywj: ^C
We can clearly see it's prompting after each '&' character it finds, even with the use of double quotes.
