Google Messages will soon consequently erase all your old OTP messages

That may change soon however in light of the fact that as indicated by XDA's Mishaal Rahman, it appears to be that Google Messages will get another element that will help you figure that out. As indicated by the tweet and going with screen captures (see underneath), it appears to be that clients will actually want to dispatch Google Messages in their favored view, implying that it will just show messages dependent on your channel like individual, offers, OTP, and that's just the beginning.

Another component is the capacity to consequently erase your OTPs following 24 hours. This implies that rather than you having to physically erase them, Google Messages will clear it for you following 24 hours, so your inbox ought to be moderately spotless. Some of the time you should keep these messages, and around there, the main technique may be better on the grounds that it'll hold those messages while covering up and sifting them behind classifications.

Lamentably, it appears to be that for the time being this component has simply been carried out to India (as should be obvious). We don't know when Google will begin making this accessible to more clients, yet it seems like a somewhat helpful component we wouldn't see any problems with having ourselves.
