Set length and character groups
Choose 8–64 characters and enable uppercase, lowercase, digits, or symbols. Exclude groups that the destination does not permit.
Remove confusing characters
You can exclude O, 0, I, l, and 1. Choose three, five, or ten suggestions at a time.
Review and copy a suggestion
Generate a fresh set or click a suggestion to copy it. Check required minimum counts for each character type separately.

A worked example

Start with: Length: 16 · lowercase only · 3 suggestions · ambiguous characters excluded
Check the result: Three independently generated 16-character suggestions appear. Lowercase l is excluded from the pool.

The actual strings change each time. This demonstrates the controls rather than recommending rules for a particular site.
