Adobe Acrobat频繁要求登录的原因包括同步设置、云存储或验证许可，解决方法有：1.使用“记住我”选项；2.避免使用云功能；3.定期保持在线；4.尝试旧版本或第三方阅读器。Adobe为管理云服务和授权，会在使用相关功能时持续验证账户，理解触发机制后可调整工作流程减少干扰。
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 (e.g., 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.
基本上就这些。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.
