This page needs JavaScript to work

JavaScript couldn't run in this view — often because a local file opened in a preview like Quick Look on iPhone or iPad, or because JavaScript is turned off in your browser's settings. Encryption 1™ needs JavaScript to encrypt or decrypt your content, so nothing below this message will work until that's resolved.

If JavaScript is turned off in your browser's settings, turning it back on will fix this.

Advanced settings

Code length

Refresh interval

Only change these if the service told you to use something other than the standard 6-digit, 30-second setup — most services never require this. If you pasted a full otpauth:// URI, its own settings are used automatically and these are ignored.

Treat this secret like a password. Anyone with it can generate valid codes for your account, same as this tool does. It's never transmitted or saved — it exists only in this browser tab until you clear it or close the page.
