What happens if you forget a deterministic password phrase?

There is no provider-side reset

Kardix does not store a recoverable copy of the phrase. If the phrase, PIN, label, or version is wrong, the output will be different.

Reduce the risk before migration

• Test recreation several times before changing an important account.
• Keep service recovery email, passkeys, or backup codes active.
• Migrate gradually instead of changing every account at once.
• Use a phrase you can reliably reproduce without making it weak.

Should you write it down?

A securely stored offline backup may be safer than relying on memory alone. The best method depends on your threat model. Do not store the phrase beside account labels or recovery codes in an exposed location.
