Password managers with email alias generation

An email alias is a unique address that forwards to your real inbox. Using a distinct alias for each service — shop.example.com gets a different address than bank.example.com — breaks the linkage between breaches. When a service is breached, they have an alias that forwards to you, not your primary email. You can disable the alias; the breach doesn't propagate to your other accounts.

Only one provider in this comparison has native email alias integration: Proton Pass, via its ownership of SimpleLogin. For users of other managers, SimpleLogin, AnonAddy (addy.io), and Fastmail masking are standalone services that can be used alongside any password manager.

Quick answer

You want email aliases integrated directly into autofill

Proton Pass — SimpleLogin integration creates aliases from the signup autofill flow; no separate app required

You want aliases with any password manager

SimpleLogin (standalone) or addy.io — work with Bitwarden, Dashlane, Keeper, or any other manager via browser extension

When it matters

Breach compartmentalisation — each service has a unique address; a breach on one site exposes an alias, not your primary email
Spam management — you can disable an alias that starts receiving spam without affecting your primary inbox
Identity separation — services you sign up for don't know your real email address, making cross-service tracking and correlation harder
Proton Pass integration — when autofill detects a signup form, Proton Pass offers to create a SimpleLogin alias for that service directly in the autofill flow; no separate app switch required

When it fails

Account recovery complexity — if you forget which alias you used for a service, recovery depends on having the alias still active or knowing which one it was
Reply-from visibility — sending a reply from an alias reveals your alias address to the recipient. Most alias services handle this; some require configuration
Alias service dependency — if SimpleLogin or addy.io changes pricing or discontinues, aliases need to be migrated. Proton's ownership of SimpleLogin reduces but doesn't eliminate this risk

How providers fit

Proton Pass is the only provider in this comparison with native email alias integration. SimpleLogin aliases are generated directly from the autofill interface on signup forms — the experience is seamless rather than requiring a separate app. Free tier includes alias creation.

All other providers — Bitwarden, Dashlane, Keeper, NordPass, LastPass — can be used alongside a standalone alias service. Bitwarden has integration settings for SimpleLogin, addy.io, Fastmail, and DuckDuckGo Email Protection that surface alias generation from within the extension.

Bottom line

Proton Pass for native, seamless alias integration. Any other provider paired with SimpleLogin or addy.io for a functional but less integrated solution. Bitwarden has the best third-party alias integration among the alternatives.
