Common errors

The requested length is too short for the selected character groups

Fix: Use a longer length so the generator can include at least one character from each enabled group.

All character groups are disabled

Fix: Enable at least one group such as lowercase, uppercase, numbers, or symbols.

The input uses unclear option names

Fix: Use simple keys like length, uppercase, lowercase, numbers, and symbols.

The user expects the same password every run

Fix: This tool generates a new random password each time unless you reuse the same output manually.

The generated password includes characters not allowed by the target system

Fix: Disable symbols or adjust the length and groups to match the system rules.
