Need Password Manager app recommendations for my iOS applications

Hey!

Do you mean macOS laptops (those made by Apple) or Windows laptops?

For macOS, Apple has recently introduced their Passwords app. It's built into the new version of the software. Info: Passwords User Guide – Apple Support (UK)

For Windows, you can consider using iCloud Passwords. This way, your passwords will securely sync between all your devices. To set it up: Set up iCloud Passwords on your Windows computer – Apple Support (UK) and use: Manage iCloud passwords on your Windows computer – Apple Support (UK)
