Last updated August 26, 2026
Steps
- 1
Open the passphrase generator tool and generate your value in the browser.
- 2
Copy the output — nothing is sent to a server; all processing is client-side.
- 3
Store secrets in environment variables or a secrets manager, never in source code.
- 4
Integrate the Java snippet below into your application.
- 5
Test end-to-end before deploying to production.
Code Example
SecureRandom r = new SecureRandom();
String[] words = {"correct","horse","battery","staple"};
StringBuilder sb = new StringBuilder();
for (int i = 0; i < 6; i++) {
if (i > 0) sb.append('-');
sb.append(words[r.nextInt(words.length)]);
