Is it safe to remove the TXT records after your Firebase domain is verified?

After the domain is verified, it's necessary to keep the DNS txt record because it's periodically checked to confirm everything is set up correctly and for the domain to keep verified.
DNS propagation is the time frame it takes for DNS changes to be updated across the Internet. A change to a DNS record—for example, changing the IP address defined for a specific hostname—can take up to 72 hours to propagate worldwide, although it typically takes a few hours.
To check a specific DNS record, you need to specify the nslookup command, an optional record type (for example, A , MX , or TXT ), and the host name that you want to check. Note: If you omit the record type, it defaults to A . The first two lines of output specify the server to which the request was directed.
I removed my firebase hosting TXT records, and after about a month or so had passed, I received an email from Firebase asking me to re-verify the domain or it will be removed. So you do need to leave them there.
