<p>
- Entropy values must be sourced from a
- <a href="https://en.wikipedia.org/wiki/Random_number_generation" target="_blank">strong source of randomness</a>.
- This means flipping a fair coin, rolling a fair dice, noise measurements etc. Do <strong>NOT</strong> use
- phrases from books, lyrics from songs, your birthday or steet address, keyboard mashing, or anything you <i>think</i>
- is random, because chances are <em>overwhelming</em> that it isn't random enough for the needs of this tool.

+ The random mnemonic generator on this page uses a
+ <a href="https://developer.mozilla.org/en-US/docs/Web/API/RandomSource/getRandomValues" target="_blank">cryptographically secure random number generator</a>.
+ </span>
+ <span data-translate>The built in random generator can generally be trusted more than your own intuition about randomness.</span>
+ <span data-translate>If cryptographic randomness isn't available in your browser, this page will show a warning and the generate button will not work.</span>

+// <div data-translate-html><em>keep em tag</em></div>

+// <span data-translate-title title="Example title"></span>

+//
+// Translate.phrasesAsJson();
+//
+// Use that template to translate the phrases into another language.
+// Leave the key the same. Change the value to the new language.

+// "<em>keep em tag</em>": "<em>keep em tag in Spanish</em>",
+// "Example placeholder": "Example placeholder in Spanish"
