Setting up autofill
PasswordEpic fills logins through Android's own autofill framework. It does not watch your screen, and the basic setup does not need an accessibility permission.
Autofill needs Android 8.0 or newer. On anything older the option will not appear at all — that is Android, not the app.
The short version
The app can take you straight there: Settings → Autofill Management → Enable Autofill. That opens the right system screen on most phones.
If it opens the wrong screen, or nothing happens, use the manual path for your brand below. This is worth knowing anyway, because Android moved this setting several times and every manufacturer renamed it.
Where the setting actually lives
Wherever the menu path leads, the screen you are looking for is this one — a list of every app that can fill passwords, with a single dot to award:

Note what else is on that list. Only one service can be preferred at a time, so choosing PasswordEpic means un-choosing Samsung Pass or Google.
Samsung
Settings → General management → Language and input → Autofill service → PasswordEpic
Samsung phones ship with Samsung Pass set as the autofill service. You may have to select None first, then choose PasswordEpic. If PasswordEpic does not appear in the list, back out to the previous screen and go in again.
Huawei and Honor
Settings → System → Languages & input → More input settings → Autofill service → PasswordEpic
Pixel and stock Android
Settings → Passwords & accounts → Autofill service → PasswordEpic
On Android 14 and newer this is often Settings → Passwords, passkeys & accounts → Additional providers.
Xiaomi, Oppo, Vivo, and anything else
The name of the screen changes, the words "Autofill service" do not. Open
Settings, use the search box at the top, and type autofill. That is far
faster than guessing the menu tree.
If you would rather navigate, one of these two usually works:
- Settings → System → Languages & input → Autofill service
- Settings → Apps → Default apps → Autofill service
Making it work in Chrome
This is the step most people miss, and the reason autofill often works in apps but not on websites.
Chrome has its own password manager, and by default it will not hand web forms to anyone else. Setting PasswordEpic as your phone's autofill service is not enough on its own.
- Set PasswordEpic as the system autofill service first, using the steps above.
- Open Chrome → ⋮ (three dots) → Settings.
- Find Autofill services and turn on "Autofill using another service".
- Confirm, then fully close Chrome and reopen it. Chrome only picks the change up on a restart.
Depending on your Chrome version this setting sits under Autofill services, under Passwords, or inside Autofill and passwords. The wording to look for is "Autofill using another service" or "Use another service".
If you cannot find it anywhere, Chrome is on a version that keeps web forms to Google Password Manager, and no third-party manager will be offered on websites.
Other browsers — Firefox, Samsung Internet, Brave — mostly use the system autofill service directly and need no extra step.
When an app refuses autofill entirely
Some apps opt out of the autofill framework. That is their decision and no password manager can override it.
There is no way around it, and you should be suspicious of any password manager that claims otherwise.
The usual trick is an accessibility service — the Android permission that lets an app read every field on screen. It would work, and PasswordEpic deliberately does not ship one.
Google does not permit the accessibility API to be used this way, and the reason is sound: it is the single most abused permission on Android, which is why this site warns you about it elsewhere. A password manager asking for it is asking you to grant the exact capability that credential-stealing malware needs.
For an app that refuses autofill, open PasswordEpic, copy the password, and paste it. Slower, and honest.
