Passphrase unavailable — desktop wallet 2023

Survives

Case description

A user with a multi-coin Electrum wallet created in 2019 attempted to restore it in November 2023 after a SSD failure. The seed phrase was available and correctly entered, but the wallet prompted for a seed extension (custom passphrase) that the user had not documented. The user had a strong recollection of the extension they used in 2019 but the exact capitalisation and special character placement were uncertain. A recovery service tested approximately 2,000 variations of the remembered passphrase over two days and located the correct extension, restoring full access.
