TLDR

Inhibit iPhone's auto-capitalization in password inputs by implementing:

<input type="password" autocomplete="off" autocapitalize="none">

By setting autocapitalize="none", prevent the initial letter from transforming to uppercase. Place autocomplete="off" to avoid browser stored data from interrupting.

Security and UX harmonization

Twisting users' experience elegantly

While thinking of fast solutions, one might tempt to change the input type to text, but that could lead to potential security challenges including exposed passwords. Always keep your password field type as "password" to maintain data confidentiality.

Disabling automatic corrections

Password fields should eliminate any form of automatic correction. Therefore, include autocorrect="off" to ensure iOS doesn't try to autocorrect passwords based on dictionary entries:

<input type="password" autocomplete="off" autocapitalize="none" autocorrect="off">

/* Try typing supercalifragilisticexpialidocious without "autocorrect" interfering 🕶️ */

Identifiers for better accessibility

Implement "id" and "name" attributes to aid with assistive technologies like screen readers, and backend form processing. Accessibility can't be an afterthought, drive towards making your components as compatible as conceivable for all users.

Sometimes, despite all our commend efforts, browser behavior can be inconsistent. Some browsers might ignore our settings due to security measures, or platform-specific behaviors. Regularly test your forms on a myriad of devices to ensure the experience consistency.

Platform-specific document perusing

For those looking to delve deeper, platform-specific documentation is a good starting point. For instance, Apple's developer guides may offer insights into specific attributes behavior. Keep in mind that compatibility can waver, and certain attributes may operate differently across various browser versions.
