Adobe Acrobat keeps asking you to sign in because it's trying to sync your settings, cloud storage, or track usage—especially if you're using features tied to Adobe ID, like cloud documents, commenting, or PDF editing across devices.

If you're seeing this constantly and it's annoying, here are a few reasons why it happens and what you can do about it.

You're Using the Free Version of Acrobat Reader or DC

Adobe has been pushing more cloud-based features and account integration, even in the free versions. If you're using Acrobat Reader DC or even Acrobat DC (the paid version), it may prompt you to sign in every so often to verify your identity or sync preferences.

What you can do:

• Sign in once and check the "Remember me" option.
• If you don't want to use an Adobe ID at all, you might be able to skip some prompts by declining during startup (but not always).
• Keep in mind that some features—like saving files to the cloud or commenting with others—require an account.

Cloud Documents and Synced Files Require Authentication

If you've opened a PDF from Adobe Document Cloud or synced your settings across devices, Acrobat will keep checking your login status to make sure you have access rights.

Common situations include:

• Opening a file shared via Adobe Sign or Acrobat Share
• Saving files to your Adobe Cloud storage
• Using Acrobat on multiple devices

To reduce sign-in prompts:

• Stick to local files stored on your computer instead of cloud ones
• Avoid syncing settings between devices
• Turn off automatic cloud sync in Preferences > General or Sign-In options

It's Part of Adobe's Licensing and Security Checks

Even if you bought a full license for Acrobat Pro DC, Adobe may still ask you to re-authenticate periodically as part of their DRM (Digital Rights Management) system. This is meant to prevent unauthorized sharing of software licenses.

This tends to happen when:

• You haven't signed in for a while
• You switch networks or use a new device
• Adobe pushes a major update or security patch

You can minimize these interruptions by:

• Signing in once and keeping your session active
• Making sure you're connected to the internet regularly (so it doesn't fall out of sync)
• Avoiding offline use for extended periods if possible

How to Stop Acrobat From Asking You to Sign In Repeatedly (Some Workarounds)

There's no guaranteed way to completely stop Adobe Acrobat from prompting you to sign in—especially if you're using newer versions. But here are a few things people have tried:

• Use an older version of Acrobat (eg, Acrobat DC 2015 or earlier), which had less aggressive sign-in requirements
• Run Acrobat in offline mode after signing in once (but cloud features won't work)
• Disable network access for Acrobat temporarily (advanced users only)
• Use third-party PDF readers like Foxit or SumatraPDF for basic viewing tasks

Keep in mind that Adobe updates its software regularly, so these workarounds may stop working over time.

基本上就這些。 It's mostly about how Adobe wants to tie your usage to an account for cloud services, licensing, and tracking. Once you understand which features trigger the sign-in prompts, you can adjust your workflow to avoid them—or accept that occasional login is just part of using modern Adobe apps.
