[Full release notes](https://github.com/dfinity/internet-identity/releases/tag/release-2026-08-19)

## Wasm Verification

To build the wasm modules yourself and verify their hashes, run the following commands from the root of the [Internet Identity repository](https://github.com/dfinity/internet-identity):

```
git pull  # to ensure you have the latest changes.
git checkout 703244a5fae6be851aa3c38a198947336781a18e
./scripts/verify-hash \
    --ii-hash 2a1e029dc5a4743a3a76eb57a0ab8bc99396bf2b49490345112bafff2fd4b423 \
    --archive-hash 03bb89037da843d1560c574a2cfbb9ec46336d9162dba30c17a2868652b0ad2d
```

## Backend Argument Verification

Run the following command to verify the backend upgrade argument hash:

```
didc encode -d ./src/internet_identity/internet_identity.did -t '(opt InternetIdentityInit)' '(null)' | xxd -r -p | sha256sum
```

The output should match the argument hash.
