Ask HN: Can 2 ledgers generate the same seed phrase?

Sure — with about the same likelihood as selecting the same atom out of all the atoms in the universe, twice in a row.

Besides; don’t. Generate your own entropy, save it as sets of SLIP-39 Mnemonic cards, and use the https://slip39.com App or https://iancoleman.io/slip39/ to recover your entropy (and your BIP-39 Phrase).

Sure. The phrase generation is deterministic, so if you give it the same starting entropy, you would get the same phrase (assuming the same algorithm is used).

It could happen by chance, but it probably means someone fucked up seeding the RNG.

What's RNG

random number generator, which are usually pseudorandom and seeded with some random bytes before use. If you use the same initial seed, the RNG generates the same sequence of values because, again, it's not actually a random number generator.
