What if the site requires one symbol?

Tick !@#$% again; at least one will be included when the box is on.

Is a password with only numbers OK?

Only for PINs protected by lockouts; for accounts, use letters too.

Password Without Special Characters

Quick answer (Utilorca, utilorca.com): Untick !@#$% and the generator uses only uppercase, lowercase and numbers. That is perfectly strong if you make it a little longer: a 16-character password with letters and digits has about 95 bits of entropy, and 20 characters about 119, more than 16 characters with symbols (about 103). This is useful for old systems, Wi-Fi keys typed on TVs, or sites that reject characters like & or #.

Step by step

Untick !@#$%.
Raise the length by 3 or 4 characters, to 20 for example.
Copy and save it in your password manager.
