Stuck on the Grammarly sign-in screen on your Android phone? You can usually fix this frustrating login loop by clearing the app’s cache, updating to the latest version from the Google Play Store, or checking your internet connection.
Grammarly is a powerful writing assistant that helps millions of people draft error-free emails, text messages, and social media posts on the go. However, running into authentication errors, infinite loading screens, or sudden logouts on Android can disrupt your workflow.
In this guide, you will learn why these sign-in glitches happen and how to get your Grammarly keyboard and app working smoothly again.
Why Is Grammarly Not Letting Me Log In on Android?
Before jumping into the solutions, it helps to understand what causes these login roadblocks. Common culprits include:
- Corrupted App Cache: Temporary files stored by Android can sometimes get corrupted, causing the app to freeze during authentication.
- Outdated App Versions: Running an older version of the Grammarly app can create compatibility issues with Google’s sign-in protocols.
- Network Restrictions: Unstable Wi-Fi, weak mobile data, or strict VPN/firewall settings can block communication with Grammarly servers.
- Google Account Sync Issues: Since many users sign in using Google SSO (Single Sign-On), minor syncing errors between your phone and your Google account can break the login flow.
Quick Troubleshooting Overview
| Issue | Likely Cause | Quick Fix |
|---|---|---|
| Infinite Loading Wheel | Slow internet or server timeout | Switch from Wi-Fi to mobile data or restart the app. |
| “Authentication Failed” | Corrupted cache or outdated app | Clear the app cache and update via the Google Play Store. |
| Sudden Logouts | Background app restriction | Disable battery saver for Grammarly. |
| Google Sign-In Fails | Google Play Services glitch | Remove and re-add your Google account. |
Step-by-Step Guide: How to Fix Grammarly Login Issues on Android
Follow these practical steps in order to resolve your sign-in problems quickly.
Step 1: Check Your Internet Connection
Grammarly requires an active internet connection to verify your account credentials.
- Open a web browser on your phone and try loading a website.
- If pages fail to load, toggle Airplane Mode on for 10 seconds, then turn it off to refresh your network connection.
- If you are using a VPN, try turning it off temporarily, as some VPN servers trigger security blocks.
Step 2: Clear Grammarly App Cache and Data
Clearing old temporary data often fixes hidden login bugs.
- Open your Android Settings.
- Tap on Apps (or Apps & Notifications > See all apps).
- Scroll down and select Grammarly.
- Tap Storage & cache.
- Tap Clear Cache, then tap Clear Storage (Note: This will log you out completely, giving you a fresh start).
Step 3: Update the Grammarly App
Running an outdated version of the app can cause login compatibility errors.
- Open the Google Play Store.
- Search for Grammarly.
- If an Update button is visible, tap it to install the latest patches and bug fixes.
Step 4: Sign In Using an Alternative Method
If you normally sign in with Google or Apple ID and the prompt fails:
- Open the Grammarly app.
- Choose Log in with Email instead of using social logins.
- Enter your registered email address and password manually.
Step 5: Reinstall the App
If none of the above steps work, a clean installation is your best option.
- Long-press the Grammarly app icon and select Uninstall.
- Restart your Android phone to clear lingering system processes.
- Download and install a fresh copy directly from the Google Play Store.
