• Uses
• In Mask mode, entropy depends on each token’s character set.
• Uniqueness is checked within this batch; increase length/alphabet if you see collisions.
crypto.getRandomValues for secure randomness.• In Mask mode, entropy depends on each token’s character set.
• Uniqueness is checked within this batch; increase length/alphabet if you see collisions.
Generated Codes
Tips
- • Masks give you structured codes (e.g.,
AAAA-9999-****). - • Length mode is great for passwords or simple vouchers. Use symbols for stronger secrets.
- • Avoid ambiguous makes codes easier to read and type.
- • No vowels helps avoid accidental words.
- • Export as TXT or CSV for import into your systems.
