Google says it is setting a 2029 target for moving its systems to post-quantum cryptography, arguing that progress in quantum computing means the industry needs to prepare now rather than wait for today’s encryption to become vulnerable. The post says the risk is not just future break-ins, because attackers could steal encrypted data now and try to decrypt it later once quantum machines are powerful enough. Google is also shifting its internal priorities toward protecting authentication and digital signatures, which it treats as especially important for a safe transition. As part of that effort, it points to work such as adding post-quantum signature protection in Android 17 and earlier support across Chrome and Google Cloud. The broader message is that Google wants to push both itself and the wider industry to move faster on upgrading security before quantum threats become practical.
