Obviously I still have access to my other keys for multisig so I can still access funds but itās a (necessary) hassle being in different locations. I have some sats on single sig though so canāt access them due to iOS so thinking I can just input seedphrase into coldcard to access those ??

What wallet are you using as multisig coordinator?
Iām not Hodl but have helped many people with this. Thereās no issue switching devices via seedphrase in most multisig setups. Just test everything a lot before disposing of/retiring the old device.
Some people are really precious about seedphrases. Personally I like to have an excuse to burn them as often as possible. Thatās just me though.
I treat them like burner emails. Precious about the security not the seed itself.
Exactly
Only thing to watch out for there (and yāall are likely too advanced for this) is if you have old addresses youāve saved personally, whitelisted somewhere, or out in the wild. Seen many people dispose of phrase(s) then get a deposit because of one of the above reasons. Even if youāre rotating devices often or phrases, thereās pretty much no reason to permanently get rid of any cryptographic material if you can avoid it.
I feel like yubikey or equivalent is preferable to whitelisting for exchange accounts.
I hate whitelisting. Itās the worst. Exchanges should speak xpubs but theyāre too busy with Polkadot staking.
Itās the fucking worst. Idk why exchanges wouldnāt want to provide internal wallet + HW functionality. The reason is likely because theyāre all highly fractionally reserved.
The step of manually entering has always felt important to me. Whitelisting feels like it encourages address reuse.
I kind of think itās hilarious to throw old metal seed plates in the trash, because I know one day someone will find it and get really excited lol š

Have you seen our latest Punchplates?
Btw, we met at whistlers(?) in Austin, you told me about the spy quarter! ;)
Our smallest one is about the size of a quarter now. Need to craft a case or something to disguise it.
Yāall are too comfortable changing seed phrases lmaoā¦do you need a new cold wallet device every time??
Not at all. That would be like needing a new device every time I changed an email address.
Ok I thought each cold wallet device made one seed phrase and that was thatā¦mind you I have the ledger
Can you please direct me to some videos and/or articles to up my security ? Thanks man
