FAQ
Is OTP Secret Generator really free?
Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.
Is anything I type into OTP Secret Generator sent to a server?
No. Every keystroke is computed with a pure JavaScript engine (Web Worker for heavy inputs) inside this page. Close the tab and your data is gone — unless you explicitly download or share it.
What should I enter in "Length"?
Put your length here — for example: 32. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.
I normally use QRTiger — why switch?
If you are tired of signup walls for high-resolution downloads and generators that log what you create, GenForge is the alternative: WebCrypto secrets, nothing logged or stored, one-tap copy and download.
How accurate is OTP Secret Generator?
Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
