# Account security > Two-factor sign-in, signing out, and how your files are protected. Source: https://docs.wavdrop.link/account-security Your account holds unreleased music, so it's worth two minutes to lock it down. ## Turn on two-factor sign-in With two-factor on, signing in needs your password and a six-digit code from an authenticator app on your phone. 1. Go to **Settings › Login & Security**. 2. Choose **Set up authenticator app**. 3. Scan the QR code with an authenticator app (Google Authenticator, 1Password, Authy and similar all work). 4. Type the six-digit code. It checks itself after the sixth digit. You can turn it off again from the same place. ## Change or reset your password - Signed in: change it in **Settings › Login & Security**. - Locked out: choose **Forgot password?** on the sign-in page and follow the email. Changing your password signs you out on every other device. ## Sign out **Settings › Session & account › Sign out** signs out this device. To sign out everywhere else too, change your password. ## How your files are protected - **Private by default.** Your audio, artwork and account data are stored encrypted, in private storage. Nothing sits at a public address. - **Checked on every play.** Each time someone presses play, WAVDROP checks the link and any password or email lock before a note streams. - **Your links, your rules.** You can turn a link off, replace it, or make it expire at any time. See [Share links](https://docs.wavdrop.link/share-links). - **No training on your music.** WAVDROP doesn't use your audio to train AI and doesn't send it to AI services. More detail is on the [Security](https://wavdrop.link/security) page, and what we collect is in the [Privacy Policy](https://wavdrop.link/privacy). ## Report a security issue Found something that looks wrong?
