One-time 6 or 8-digit passwords for two-factor authentication and testing
An OTP generator creates a one-time authentication code โ a short random combination used for confirming actions, two-factor authentication and test scenarios. One-time codes add a layer of protection because they are valid only once and are not reused.
The tool is handy for developers and testers who need sample OTP values, and for anyone learning how one-time codes work. You can choose the length and character type โ digits only, letters with digits, or hexadecimal. Everything works online without sign-up.
Choose the code length and character type, then press the generate button. The one-time code appears instantly โ copy it or generate a new one as many times as you need.
