How do I use it on my desktop or laptop then? What if I switch browsers on my phone? What if I get a new phone? What if I change from android to iOS or visa versa? What if I need to log into the site on my Wii U's browser?

You can let Apple sync your passkeys between devices using iCloud Keychain. Then you can create a passkey on one device and have it available on all of your devices. Google also syncs passkeys to the cloud and lets you use them on Windows (with Chrome)

>What if I change from android to iOS or visa versa

I resolve this by storing most of my passkeys in my password manager. I still store the "important" ones (like online banking) in my phone so a password manager breach doesn't make me lose my money.

Passkeys were designed to let you have more than one, so if you have a device that doesn't let you use your password manager, then just set up another passkey.

Nothing wrong with your answer itself, but having to be Apple or Google is a PITA. These account are ultra critical already and you will want maximum security to access them.

This means if you go on a trip somewhere you absolutely need two devices. If you kill your phone and want to buy another one ASAP, you wont be able to do anything with the new device until you can convince the platform it's you. With passkeys you're just SOL. Imagining if you needed a phone to get back from your trip - e.g. etickets, auth needed etc. - it becomes a nightmare scenario.

A third party manager makes it easier, but it's a lot less usable that the first party ones.

Reasonable people make different life choice, having to constantly think about backup strategies whenever I'm away from home would be so stress inducing to me.

  > With passkeys you're just SOL.
No more so than if you lose access to the device that's required for Google/Apple MFA prompts, neither of which use SMS and depend on a proprietary approval flow.

If you lose your phone in 2026 while on a trip to Italy and try to enter your Gmail user/pass from your wallet, there's about a 100.00% chance you'll hit a "let's verify you're you" gate, that's been the case for 5+ years.

With passkeys I'm not stuck clicking Yes in the Gmail app or typing in the numbers on Apple hardware, I can skip the Apple/Google specific MFA nonsense and keep the passkeys in Bitwarden where they sync seamlessly between devices.

It feels truly liberating being able to skip MFA everywhere and login with 1 click, like a throwback to the golden age of using a password manager in 2010. Before passkeys it started to feel like I was spending 5% of my waking hours every day copying 6 digit codes from phone/email/TOTP after twiddling my thumbs for 15-30 seconds.

If you want multi-device redundancy, you have to carry a second device of some type, it's hard to get around that. I almost always travel with an iPad in addition to my phone, so I have a second device.

In addition, my wife (who travels with me so if my iPhone is stolen, hers might be too) is one of my Apple account recovery contacts, plus I've set my sister as an addtional recovery contact, so even if I'm out of the country and I have to activate a new iPhone, I can call her to help with the recovery. So all I have to do is find an Apple store and buy a new phone.

I also carry a USB key tucked into my luggage with the recovery kit (encrypted) for 1Password so I can activate 1Password on any new device and have access to my passwords and whatever passkeys I don't have in iCloud.

I just don't use Google or Apple accounts for everything. I don't want my whole life in the hands of some big tech deciding how I should prove to them that I'm me.

I did use Microsoft 365 (business version) for my email but they also decided I should use their MFA app so I left. I did have my yubikey as second factor but they keep pushing their stupid authenticator app.

Apple can sync to my wii u?

I updated my reply to be more complete.

as long as you have one working device all will be OK. Either you scan the QR code shown by the website. or if you did login to Chrome with google account then desktop or laptop will just sign you -friction less. Same with iCloud account.

If you browser vendor has implemented passkey then all good.

Most things are built for the majority users. Most don't change. Most don't debate browser wars in hn. Life is like that.

For Wii etc. You just scan the QR code shown in the TV interface. all just works.

Yes, if you want 100% privacy and will do only your own dovecot server then it is not for you.
