Getting a recovery key in the Yoti app will help you to recover any saved passwords in future. To get your recovery key, tap on More tab > Settings > Account Settings > My Recovery Key. By storing your recovery key in iCloud or Google Drive you protect all of your Yoti data, including your logins, and can recover them if you lose your phone, it gets stolen or if you reinstall the app.
You can also export your saved logins when using Yoti Password Manager on your desktop browser. Just go to Settings and click Export saved logins to download a copy of all your logins as a CSV file.
