AliasVault

Very sophisticated app frees us from having all security eggs in one basket—and is FOSS, replete with very valuable features, available on any platform you can hope for--which also makes it redundant and therefor more fail-safe way to keep your access credentials, well, accessible—and intuitive to use. Even the import guide, such as for duplicating other vaults/keychains is superbly helpful. Quite a fine-looking website, too! 😄 Do yourself a favor and just start using it...but do the world a favor and "buy this dev a coffee" (there's a donation link on the app's F-Droid page—main repository! 🤯).
