Many SMS sent via cellular networks work as one-time passwords. To ensure that messages don’t remain on your phone, you can also delete SMS storage. Google has redesigned its Messages app. The update will initially only be available in one country.
A Google Blog entry shows that the Messages App for Android now can automatically classify incoming SMS. These messages can be classified as “Personal”, “Transactions”, “OTPs”, and “Offers”. Personal SMS is sent from the stored contacts. Banks send messages about transactions and one time passwords. The smartphone does the classification so the messages don’t have to be sent to Google servers.
This allows messages to be correctly classified even if there is no internet connection. At the user’s request, one-time passwords (OTPs), can be deleted automatically. After 24 hours, the SMS will be deleted from the smartphone. OTPs can only be used once to register for a service so the messages will no longer be needed afterwards.
India is the only country that features this feature at the moment
The current classification function only filters messages sent to Indian users. Only English-language SMS are accepted. The user must have Android8 installed on their device to receive the update. The feature will be made available to all users worldwide later in the year. However, it is not known when.
