WA Backup logo WA Backup

Your WhatsApp history, backed up properly.

Chats, photos, videos and documents saved to your own private cloud. Encrypted on your phone before anything leaves it.

Start the setup

The app, installed

WA Backup on the same Android phone that runs your WhatsApp.

An account

Your email plus a password of at least 8 characters. Created in the app in seconds.

Your 64-digit key

WhatsApp's encrypted-backup key. Step 4 shows exactly where to find it.

Set up in six steps

About five minutes from install to first backup. After that, everything runs on its own.

Step 1

Create your account or sign in

Open the app, enter your email and a password of at least 8 characters, then tap Register. Already registered? Sign in instead.

Forgot your password? Tap Forgot password and a 6-digit reset code is emailed to you.
Step 2

Grant storage access

Tap Grant storage access and allow the permission Android asks for. The button changes to Access granted once it works. This lets the app read the WhatsApp folder:

Folder the app reads
Android/media/com.whatsapp
Step 3

Enter your WhatsApp number

Type the number you use with WhatsApp, including the country code, for example +91 98765 43210. It labels your backups so you always know which phone they came from.

Step 4

Find and enter your 64-digit key

WhatsApp protects backups with a 64-digit key. To view yours, open WhatsApp and follow:

  1. Go to Settings, then Chats, then Chat backup
  2. Tap End-to-end encrypted backup and turn it on if it is off
  3. Choose Use 64-digit encryption key instead, then Generate your 64-digit key
  4. Tap View 64-digit key and copy it carefully

Back in WA Backup, paste the key into the key field. Spaces are removed automatically; the app just needs all 64 characters (digits 0 to 9 and letters a to f).

Write this key down somewhere safe. It is the only thing that can unlock your backups. If it is lost, nobody can recover your chats, including us.
Step 5

Save and start your first backup

Tap Save & start backup. The app uploads your encrypted chat database exactly as WhatsApp stored it, then your media, encrypted on your phone first. Every later run uploads only what is new.

The first run can take a while with years of media. Keep the phone on Wi-Fi and charging; later backups are much faster.
Step 6

Browse your archive

Open the Chats tab to read every backed-up conversation, view media and statuses, and manage old snapshots. Everything is decrypted on your device with your key, never on the server.

Built so we cannot read your chats

Not a promise, a design constraint. The server only ever holds locked files it has no key for.

Your key never leaves your phone

The 64-digit key is stored in your phone's hardware keystore. It is never uploaded; the server only knows your phone number label.

Encrypted before upload

Chats stay in WhatsApp's own encrypted format and media is encrypted on your device first. The cloud stores locked files only.

Decrypted only on your screen

When you browse your archive, files come down still locked and are opened locally with your key. Nothing readable ever sits on the server.

Common questions

The app says "Enter the full 64-digit hex key". What is wrong?
The key must be exactly 64 characters using only digits 0 to 9 and letters a to f. WhatsApp shows it in small groups (like 4cfs s4ds); that is fine, spaces are stripped automatically. Check you copied every group and did not confuse the letter o with the digit 0. The key never contains the letter o.
Do I need to keep the app open during backup?
Keep it open for the first large backup. After that, runs are incremental and quick because only new messages and media are uploaded.
What happens when I get a new phone?
Sign in with the same email and password, grant storage access, and enter the same 64-digit key. Your cloud archive stays intact and the new phone can both read it and keep backing up to it.
I lost my 64-digit key. Can you recover my backups?
No, and that is deliberate. The key never leaves your device, so no copy exists anywhere that could unlock your data. Generate a new key in WhatsApp, enter it in the app, and start a fresh backup. This is why we ask you to write the key down during setup.
How much data does a backup use?
The first backup uploads your chat database plus the media in your chosen range, so it depends on how much media you have. Every run after that uploads only new files. Use Wi-Fi for the first one.
Can I delete old backups?
Yes. Open the snapshots list in the app and delete any snapshot you no longer need. Both the stored file and its record are removed from the cloud.
