๐ Backup Code Generator
* Generated codes are lost when you leave this page โ store them somewhere safe if you need them.
Generate a batch of random backup codes, similar to the recovery codes issued for two-factor authentication (2FA). Uses a character set with ambiguous characters removed (like 0/O and 1/I) so the codes are easier to read and re-type accurately.
How to use
- Enter how many codes to generate.
- Click "Generate" to see a list of random backup codes.
- Use the "Copy" buttons to copy an individual code or all of them โ store them somewhere safe.
FAQ
Are the generated codes saved on this site?
No. Generation happens entirely in your browser and nothing is ever sent or stored anywhere. Results disappear when you reload the page, so copy them somewhere safe while they're displayed if you need them.
Can I use these in place of an actual service's 2FA backup codes?
No โ codes generated here aren't registered with any real service's system, so they won't work for that service's authentication. Use this for generating your own standalone backup codes or for testing purposes.
Why are ambiguous characters excluded?
Characters that are easily confused when handwritten or printed โ like the digit 0 vs. the letter O, or the digit 1 vs. the letter I โ are excluded to reduce typos when entering a code manually.
