Private Key Recovery, Done Right

By the BMIC Research Desk · Updated 2026-08-29 · Part of the BMIC Wallet Guide series
Quick answer: Recovery for a self-custody wallet works through a seed phrase, recorded once at setup and kept offline on paper -- never a screenshot or cloud note. It is the only backup mechanism: lose it, and no support desk anywhere can restore access.

Recovery is where most wallet security mistakes actually happen -- not in the cryptography, but in how the backup itself is handled.

When BMIC generates your seed phrase at setup, write it on paper, not a screenshot and not a note app. A screenshot can sync automatically to a photo backup you don't fully control; a note app can sync to a cloud account with its own separate security exposure.

Store that paper somewhere fire-safe and physically separate from the device it protects. If the device is lost, damaged, or replaced, the seed phrase alone restores full access on a new one -- that is the entire recovery model for a self-custody wallet.

There is no password reset, no email link, and no support ticket that can bypass it, by design. That is the deliberate trade every self-custody wallet makes: nobody else holds a copy of your key, which also means nobody else can hand it back to you if the seed phrase itself is lost.

FAQ

Can BMIC support recover my wallet if I lose my seed phrase?

No. There is no second copy held anywhere else -- the seed phrase is the only recovery mechanism, by design.

Is it safe to store a seed phrase as a photo?

Most security guidance advises against it -- photos commonly sync to cloud backups, turning an offline secret into a networked one.

What if my device is lost or damaged?

The seed phrase alone restores full access to the same wallet on any new device -- that is the entire purpose of recording it at setup.

Should I split my seed phrase across multiple locations?

Some people do, for physical redundancy -- the trade-off is more locations that each need to stay both safe and offline.
