Do you want to download apps without having to enter your Apple ID password? You can do this by enabling Touch ID or Face ID in the settings. To do this, go to Settings and scroll down to iTunes & App Store. Tap Password Settings and enter your Apple ID password. This will only affect free purchases, so you will still need to enter a password or use Touch ID for any monetary transactions.
You can also use an alternative app like iOS Emu or TuTu Helper to download apps without having an Apple ID. If you try to purchase an app, the password request will appear again. Here's how you can download apps without an Apple ID password.
